Europe/Rome Abstract: After a brief introduction to the synthetic notions of Ricci curvature lower bounds in terms of optimal transportation, due to Lott-Sturm-Villani, I will discuss some applications to smooth Riemannian manifolds (joint work with Fabio Cavalletti, SISSA). These include: rigidity/stability of the Levy-Gromov inequality and an almost euclidean isoperimetric inequality motivated by the celebrated Perelman’s Pseudo-Locality Theorem for Ricci flow.

This year, the Workshop is about recent progress in electronic structure methods and their applications. The aim is a critical discussion of methods and of possible combinations and challenging applications. It has become one of the most popular regular events of the international ab-initio electronic structure community. This event also has the ambition to reach out to countries where the electronic structure community is not traditionally as strong as in Europe, the USA and Japan, in coherence with the missions of its traditional host institution, the ICTP.

Europe/Rome Abstract: In this talk we will prove that some abelian surfaces are modular, in the sense that there is a paramodular form whose L-series matches that of the abelian surface. During the talk we will recall the relation between automorphic representations and algebraic varieties (with special emphasis in the case of abelian surfaces), and will describe in detail the Faltings-Serre method (and its relation with deformation theory). The talk will be self contained, and only some knowledge on Galois theory will be assumed. ICTP ICTP pio@ictp.it

Europe/Rome Several million chemical compounds are known, but with 118 chemical elements the number of compounds that are stable and could be synthesized is potentially much larger. The Workshop focuses on recent developments in the prediction of crystal structures by computational methods. Thanks to enormous progresses in computational power and in algorithm development, we are now closer to the possibility to predict the structure of a material from the simple knowledge of its composition. This Workshop will be dedicated to presenting and discussing the algorithms for in-silico crystal structure prediction that were developed in the last years, focusing in particular on the approaches based on molecular modeling. We find particularly appropriate holding this conference in 2019, the International Year of the Periodic Table, since crystal structure prediction is rooted in a deep knowledge of the properties of the atoms. The Workshop will be divided into two parts: the first 3 days will be dedicated to an advanced discussion of the latest advances in the field and last 2 days will be dedicated to hands-on tutorials with structure prediction methods in combination with electronic structure and atomistic methods. A Poster Session will also be organized, and interested candidates are invited to upload a short abstract of their proposed posters during the application process (max. half page, in pdf format). Poster presentation is not mandatory, however participants are encouraged to present their results.

Europe/Rome Quantum optimal control allows finding the optimal strategy to drive a quantum system in a target state. We review an efficient algorithm to optimally control many-body quantum dynamics and apply it to quantum annealing, going beyond the adiabatic strategy. We present an information theoretical analysis of quantum optimal control processes and its implications. We review some recent advancements we have obtained in tensor network algorithms that enable such investigations and that can be exploited to support the development of quantum technologies via classical numerical simulations: novel approaches to study abelian and non-abelian lattice gauge theories, open many-body quantum systems and systems with long-range interactions or periodic boundary conditions. Finally, we report some theoretical and experimental applications of these approaches to relevant scenarios, such as Rydberg atoms in optical lattices and the gauge theory resulting from the mapping of classical hard problems to short-range quantum Hamiltonians.

Europe/Rome Mike Glazer is Emeritus Professor of Physics at the University of Oxford and Visiting Professor at the University of Warwick. He was born on May 1st 1943. His PhD research between 1965 and 1968 was under the supervision of Kathleen Lonsdale at University College London, working on the crystallography of organic mixed crystals. In 1968-1969, he was a Fellow at Harvard University, and then from 1969 to 1976 he was at the Cavendish Laboratory, Cambridge. In 1976, he was appointed Lecturer in Physics at the Clarendon Laboratory Oxford and as an Official Fellow and Tutor at Jesus College Oxford. Mike Glazer's research has mainly been in understanding the relationship between physical properties of crystals and their structures. He is perhaps best known for his classification system for tilted octahedra in perovskites. He is also one of the co-founders of Oxford Cryosystems Ltd, which supplies the world market in low-temperature apparatus for crystallographers. He is currently Editor of the Newsletter of the International Union of Crystallography. Abstract: The field of Crystallography is one of the oldest of scientific disciplines, and yet it continues to make important advances today and into the future. In this talk, I will trace the history of some important ideas that have led to some basic understanding of the structures of crystals before experimental techniques evolved to enable these theories to be tested. In the 20th century, the discovery of X-ray diffraction by crystals has led to the formation of a whole new discipline, namely X-ray Crystallography. This discovery has since then expanded to include neutron and electron scattering and has increased our knowledge of materials and biological systems. As a result, many Nobel Prizes have been awarded for work relying on crystallographic studies. Over the last 100 years many new experimental techniques have arisen, including the use of synchrotron radiation, free electron lasers and very recently major advances in the use of electron microscopes.

Europe/Rome Abstract: The category of Soergel bimodules plays an essential role in (higher) representation theory and for the construction of homological invariants in knot theory. The aim of this talk is to present a generalization of Soergel category attached to a Coxeter group of type A_2. While Soergel category counts a generating bimodule per simple reflection, this generalization is obtained by taking one generator per reflection. I will give a complete description of this category through a classification of its indecomposable objects and study its split Grothendieck ring. This gives rise to an algebra which is a quotient of the corresponding affine Hecke algebra of type A_2, that can be presented by generators and relations. This is joint work with Thomas Gobet.

Europe/Rome One key feature of the Internet of Things is the ability to rapidly create IoT applications, including scientific ones. This will allow collecting data from dozens, or even hundreds of low-cost, low-power scientific instruments. The lack of scientific data is an issue especially in Developing Countries, where the number of monitoring stations in limited and where data is unreliable due to lack of connectivity/intermittent power supply/poor maintenance. In order to address this demand, we propose the use of low-cost and low-power IoT nodes to complement the already deployed high-cost sparse networks for scientific data collection. While the IoT array will have inferior measurement accuracy due to the low-cost nature of the sensors, the high spatial density of the array is unique and will prove invaluable for research and operational applications. This workshop is intended to share good practices on how IoT nodes can be rapidly prototyped to carry out scientific measurements. Following a seven days hands-on technical workshop, participants will focus for two days on the requirements to develop three applications: radiation monitoring, oceanographic devices and weather stations. On the last day, the participants will share the results of their discussions/experiments. A basic knowledge of the Python language will be highly appreciated. TOPICS: Prototyping of embedded boards Introduction to microPython LoRa and LoRaWAN protocols Characteristics of analog and digital sensors Collection, analysis and the visualization of data Sensor requirements for radiative and oceanic monitoring and weather stations GRANTS: A limited number of grants are available to support the attendance of selected participants, with priority given to participants from developing countries.

Europe/Rome Joint ICTP-SAIFR/ICTP School on Mathematical Models of Evolution January 21 – 26, 2019 Although new experimental technology is partly responsible for the current revolution in biological research, theoretical models developed by physicists are also playing an important role in changing the way biological research is being performed. The number of theoretical physicists and applied mathematicians migrating into biology has dramatically increased throughout the world, but South America still lags behind. The one-week school on mathematical models on evolution, co-organized with the ICTP-SAIFR, UNESP, FAPESP and IFT-UNESP, will feature lectures by physicists and applied biologists who have made important contributions to this area of biological research. The school is intended for graduate students and postdoctoral researchers in the physical and biological sciences. This activity will be preceded by the ‘VIII Southern-Summer School on Mathematical Biology’. Candidates may apply either for one or both schools, and preference will be given to PhD students in South America. There is no registration fee and limited funds are available for travel and local expenses. Lecturers and courses: Population genetics and evolution – Luca Peliti (SMRI, Italy) Understanding how genetic information is transmitted across generations is at the basis of evolutionary theory. This course will review the mechanisms of reproduction, selection, mutation and drift and will be the backbone for the more specific courses below. Evolution of individuality – Paul Rainey (IAS – Massey University, New Zeland) The origins of multicellularity and cell differentiation are profound problems in biology.

Europe/Rome Several atomic, molecular, and optical systems, as well as certain condensed matter models, exhibit long-range interactions that decay with distance r as a power law 1/rα. In this talk, we will present recent results for the localization properties of correlation functions of these long-range quantum models in the presence of disorder. The latter is usually associated with exponential localization of wave functions and correlations. We demonstrate that in most situations in 1D power-law interactions imply algebraic decay of correlations. We will discuss the generality of these results and their application to experiments in atomic and molecular physics. SISSA, Via Bonomea 265 ICTP pio@ictp.it

Europe/Rome The Abdus Salam Distinguished Lectures 2019 will be given on 28, 29 and 30 January 2019 by Prof. Juan Maldacena, from the School of Natural Sciences at IAS, Princeton, USA. Juan Maldacena’s work focuses on quantum gravity, string theory, and quantum field theory. He has proposed a relationship between quantum gravity and quantum field theories that elucidates various aspects of both theories. He is studying this relationship further in order to understand the deep connection between black holes and quantum field theories, and he is also exploring the connection between string theory and cosmology. The tentative schedule for the lecture series is as follows: Monday 28 January 2019 at 16.30 hrs Lecture 1: Quantum mechanics and the geometry of spacetime. Abstract: Black holes are fascinating objects which pose interesting puzzles for quantum physics. Studying these puzzles we are led to quantum mechanical models that describe special black holes as seen from the outside. Extrapolating from these descriptions we are lead to the idea that entanglement can create geometric connections or wormholes. Moreover, quantum teleportation can be interpreted as travelling through the wormhole. Tuesday 29 January 2019 at 16.30 hrs Lecture 2: Toy models for black holes. Abstract: We will review the Sachdev Ye Kitaev model and describe how it shares some features with nearly extremal black holes. We also describe the dynamics of nearly extremal black holes. We will go over different physical phenomena, including chaos, quantum teleportation, etc, and their common manifestation in these two systems. Wednesday 30 January 2019 at 11.00 hrs Lecture 3: Toy models for black holes (part two). This will be a more technical talk based on lecture 2 above. All lectures take place in the Budinich Lecture Hall, and will be livestreamed from the ICTP website. Light refreshments will be served after the talks. All are most welcome to attend.

Then we will concentrate on some of the classical results making special emphasis in the behavior of this operator in the context of Lp spaces with weights. Then we will explain some more recent results focusing in the context of Lorentz spaces which are very useful extensions of the Lebesgue spaces. We have obtained some new results for these spaces but we don't know if they are optimal. In the last part of the lecture we will discuss a very interesting variant of the Hardy-Littlewood maximal function which is more singular called the strong maximal function. We will discuss briefly some classical results and we will mention some recent results which, again, we don't know if the are optimal. ICTP ICTP pio@ictp.it

Europe/Rome What is the nature of phase transitions in driven quantum systems? We address this question in two opposite regimes, a rapidly periodically driven Floquet system coupled to a bath and a slowly driven one, within a non-equilibrium renormalization group approach. In the periodically driven case, the infinitely rapidly driven limit exhibits a second order phase transition analogous to a multi-mode laser. However, we reveal that fluctuations turn the transition first order when the driving frequency is finite. This can be traced back to a universal mechanism, which crucially hinges on the competition of degenerate, near critical modes associated to higher Floquet Brillouin zones, in some analogy to the Halperin-Lubensky-Ma or Coleman-Weinberg mechanism. A physical picture is that of a fluctuation induced many-body Kapitza pendulum. The critical exponents of the infinitely rapidly driven system -- including a new, independent one -- can yet be probed experimentally upon smoothly tuning towards that limit. The opposite, slowly driven limit, is governed by the Kibble-Zurek mechanism of diabatic freeze out of the divergence of the correlation length. Recasting this problem in a systematic RG formulation, we show that the slow drive can be used to resolve not only the leading critical exponents of the underlying equilibrium problem, but the full critical exponent spectrum.

Europe/Rome Abstract. We discuss relativistic corrections to large scale structure observables. These are expected to yield contributions comparable to fNL of a few, and therefore potentially observable in future surveys. We then focus on the large scale structure bispectrum in the squeezed limit, which couples large with small scales. Since relativity is important at large scales and non-linear loop corrections are important at small scales, the proper calculation of the observed bispectrum in this limit requires a non-linear relativistic calculation. We compute the matter bispectrum in general relativity in the weak field approximation. The calculation is as involved as existing second-order results. For the bispectrum, we find relativistic corrections to be as large as the newtonian result in the squeezed limit. In that limit relativistic one-loop contributions, which we compute for the first time, can be as large as tree level results and have the sa dependence as a primordial local non-Gaussianity signal where k is the momentum approaching zero. Moreover, we find the time dependence of the relavistic corrections to the bispectrum to be the same as that of a primordial non-Gaussianity signal. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: The idea of studying rational maps by looking at the syzygies of the base ideal is a relatively new idea that has now become an important research topic. In this talk, we will discuss some recent results that lead to birationality criteria and formulas for the degree of rational maps that depend on the algebraic properties of the syzygies of the base ideal. Mainly, we will introduce a new algebra called "saturated special fiber ring" and we will discuss its relations with the degree and birationality of rational maps between irreducible projective varieties. Time permitting, we will also discuss some results in the problem of specializing the coefficients of a rational map. This talk is based on joint works with Laurent Busé and Carlos D’Andrea and with Aron Simis. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: The problem of understanding the global symmetries of non-holonomic mechanical systems is quite difficult. One possible approach to tackle the problem from an algebraic point of view was proposed by N. Tanaka in the 70s, through the process known as (Tanaka) prolongation. The output of the prolongation is a graded Lie algebra, whose dimension is an upper bound for the dimension of the space of symmetries. A system is called rigid if its prolongation is finite dimensional. In this talk, I will show the generic rigidity of a wide class of non-holonomic systems of step 2 (so-called Carnot groups).

Europe/Rome In this talk I will review our ongoing activity on twisted bilayer graphene at the first magic angle. I will first discuss the constraints on a low energy description put forth by the spatial symmetries of the Bloch wavefunction obtained through a realistic tight-binding calculation performed on a relaxed structure. Next I will propose a minimal tight-binding model that reproduces the elementary band representation of the emergent P622 low-energy space group. Finally, I will show how the emergent symmetry shows up in the phonon spectrum, which suggests the intriguing possibility of an Exe Jahn-Teller effect as a possible mechanism to split the so-called valley degeneracy.

Europe/Rome The fast growing use of quantum theory in technology-oriented and information-related fields is attracting the interest of an increasing number of researchers, especially young ones. The reborn interest in quantum physics has created a unique framework in which theoretical and experimental physics can fruitfully dialogue with information theory and computer science. The School intends to convey such an interdisciplinary spirit to graduate students and young researchers and will focus upon three themes, i) Quantum dynamics in the macro-world: quantum coherence and entanglement ii) Quantum theory as an interdisciplinary paradigm: quantum information and simulation iii) Quantum physics as a technology boost: quantum devices and machines emphasizing their inter-relations and covering the relevant background material, that will be taught by nine renowned experts in the above fields. The School is followed by a more specialized Workshop in which students attending the School are invited to participate.

Europe/Rome The determination of four-point correlation functions of two-dimensional lattice models is of fundamental importance in statistical physics. In the limit of an infinite lattice, this question can be formulated in terms of conformal field theory (CFT). For the so-called minimal models the problem was solved more than 30 years ago, by using that the existence of singular states implies that the correlation functions must satisfy certain differential equations. This settles the issue for models defined in terms of local degrees of freedom, such as the Ising and 3-state Potts models. However, for geometrical observables in the Fortuin-Kasteleyn cluster formulation of the Q-state Potts model, for generic values of Q, there is in general no locality and no singular states, and so the question remains open. As a warm-up to solving this problem, we discuss which states propagate in the s-channel of such correlation functions, when the four points are brought together two by two. To this end we combine CFT methods with algebraic and numerical approaches to the lattice model. SISSA, Via Bonomea 265 ICTP pio@ictp.it

Europe/Rome Using arguments from theoretical physics, Vafa and Witten gave a generating function for the Euler numbers of moduli spaces of rank 2 coherent sheaves on algebraic surfaces. These moduli spaces are in general very singular, but they carry a perfect obstruction theory (they are virtually smooth). This gives virtual versions of many invariants of smooth projective varieties. Such virtual invariants occur everywhere in modern enumerative geometry, like Gromov-Witten invariants and Donaldson Thomas invariants, when attempting to make sense of the predictions from physics. We conjecture that the Vafa-Witten formula is true for the virtual Euler numbers. We confirm this conjecture in many examples. Then we give refinements of the conjecture. Our approach is based on Mochizuki's formula which reduces virtual intersection numbers on moduli spaces of sheaves to intersection numbers on Hilbert schemes of points. ICTP ICTP pio@ictp.it

Europe/Rome Mathematical and statistical modelling of complex systems is one of the key methods to understand and master their complexity. In this talk, I will first show how Bayesian machine learning can be combined with mathematical logic (specifically, temporal and spatio-temporal logic) to provide effective tools to analyse the behaviour of complex systems, unveiling their emergent properties, and to tackle system design parameter synthesis, and model identification. In the second part of the talk, I will discuss some work in progress, extending the previous ideas to tackle (related) problems like: automatic learning of model abstractions, using also Deep Neural Networks, with applications in multiscale modelling in systems biology and in geophysics, and learning of logic-based classifiers in the context of explainable Al.

Europe/Rome This special ICTP QLS Colloquium will be given by Prof. Tatyana Sharpee. The talk on Hyperbolic geometry and symmetry breaking in neural circuits will take place in the Euler Lecture Hall, on Friday 1 March 2019 at 11.00 hrs and will be followed by light refreshments. Prof. Sharpee received her MSc degree in Theoretical Physics from Ukraine National University, Kiev, Ukraine and a Ph.D. in Theoretical Physics form Michigan State University. She turned from Condensed Matter physics to neuroscience early on in her career, first at UC San Francisco, then at UC San Diego and lately at Salk Institute where she is Associate Professor. Prof. Sharpee has been elected Fellow of the American Physical Society for "advancing our understanding of how neurons represent sensory signals and make decisions". Sharpee's work aims to develop a unifying theory of how biological systems process information. Specifically, she is uncovering how animals sense and adapt to their environment, as well as make predictions and decisions. To do this, she applies methods from physics, mathematics and information theory to chart the principles by which the brain's billions of neurons exchange energy and information. Abstract: A long standing idea in neuroscience is that the brain is adapted to the statistics of signals from the natural environment, and in some cases, as in the sense of smell, the brain and the natural environment have co-evolved together. I will first discuss how hyperbolic geometry can help provide coordinates for natural odors that offers insights into how we perceive smells. Then, I will briefly summarize our progress in mapping the hierarchy of transformations for visual signals in the brain. Finally, I will discuss how symmetry breaking and ideas from the theory of phase transitions can help systematize complexity of cell types that together provide accurate analogue representations of incoming signals using binary outputs. I will conclude with applications of these ideas to biological problems outside of neuroscience. ICTP ICTP pio@ictp.it

Europe/Rome West African climate is characterized by complex atmospheric dynamics and growing anthropogenic pressures. These pressures, combined with climate change and variability, have many environmental impacts. Regional climate models include now capabilities such as interactive coupling with oceans, surface hydrology, atmospheric chemistry and biogeochemical cycles. Combined with process study and observation analysis, such systems are interesting frameworks for impact assessments over West Africa. However their complexity is such that they require high computing power and appropriate “know-how”. This point has motivated the recent development of a supercomputing center at the University of Abidjan. In this context, the school proposes theoretical and practical computing sessions on regional climate and environmental modeling. It is co-organized with the final conference of the DACCIWA project (https://www.dacciwa.eu/) so that participants can benefit from both of these events. Participants are required to have a pre-existing background in Atmospheric / Earth system science and be familiar with Linux/Unix environment.

Europe/Rome The tropical Atlantic has warmed in recent decades, in particular in the equatorial and coastal upwelling regions. This warming was not directly forced by local heat exchange with the atmosphere, and also wind stress in the tropical Atlantic that drives oceanic upwelling rather increased than decreased. Remote forcing from outside the tropical Atlantic might thus have played a role. In this presentation, the contribution of different potential drivers is assessed utilizing a series of hindcast and sensitivity experiments with a high-resolution ocean model. It is shown that both an increase in the inflow of warm Indian Ocean waters through Agulhas leakage and a slowdown of the Atlantic Meridional Overturning Circulation (AMOC) can lead to a general warming in the tropical Atlantic ocean. Compared to a control simulation, an experiment in which Agulhas leakage was artificially increased by strengthening the Southern Hemisphere Westerlies shows a pronounced warming trend in the upper tropical Atlantic Ocean. The SST pattern that arises in response to an idealized slowdown of the AMOC due to enhanced freshwater input around Greenland is reminiscent of the observed warming trend. In this context, the role of the Atlantic subtropical-tropical cells (STCs) and in particular the strengthening of the northern cell is discussed. Mean pathways and transports between the subtropical and tropical Atlantic Ocean are also inferred from Argo observations for the last decade. ICTP ICTP pio@ictp.it

Europe/Rome Abstract. String compactifications are essential for connecting string theory to low energy particle physics and cosmology. Moduli stabilisation gives rise to effective Lagrangians that capture the low-energy degrees of freedom. Much recent interest has been on swampland consistency conditions on such effective field theories - which low energy Lagrangians can arise from quantum gravity? Furthermore, given that moduli stabilisation scenarios often exist in AdS space, we can also ask: what do swampland conditions mean in the context of AdS/CFT? I describe work on developing a holographic understanding of moduli stabilisation and swampland consistency conditions. I focus in particular on the Large Volume Scenario, which is especially appealing from a holographic perspective as in the large volume limit all its interactions can be expressed solely in terms of the AdS radius, with no free dimensionless parameters.

Europe/Rome Prof. Ignacio Cirac from the Max-Planck Institut für Quantenoptik, Germany, will give an inaugural lecture on "Quantum Simulations and the difficulty of solving Quantum many-body systems" within the ceremony for the launch of the new Trieste Institute for the Theory of Quantum Technologies (TQT), a new initiative between ICTP, SISSA and the University of Trieste. The ceremony starts at 11.00 on Monday 25 March 2019 in the Budinich Lecture Hall and will include the signing of the Memorandum of Understanding by the Directors of the three institutes. The new Institute for the Theory of Quantum Technologies has been established as a joint venture to address the significant and growing number of researchers working in the field of the so-called "Quantum Technologies" in universities and research institutions in the region, taking into account the high quality of scientific production in this field and the need to unite and coordinate activities and skills into an Inter- organizational Institute. "TQT" will be an international centre of excellence promoting theoretical research in the field of Quantum Technologies, serving as a catalyst for theoretical activities not only in Italy, but also in the neighbouring regions of the former Eastern Europe reaching out to also engage developing countries. The talk will be livestreamed from the ICTP website. ABSTRACT: Quantum many-body systems are very hard to simulate, as computational resources (time and memory) typically grow exponentially with system size. However, quantum computers or analog quantum simulators may perform that task in a much more efficient way. In this talk, I will first review some of the quantum algorithms that have been proposed for this task and then explain the advantages and disadvantages of analog quantum simulators. I will also describe the development of tensor network methods for that task, as well as a theoretical proposal to solve quantum chemistry problems with an analog simulator based on atoms in optical lattices. Light refreshments will follow the event. All are welcome to participate. ICTP ICTP pio@ictp.it

**DEADLINE: 06/01/2019**

Europe/Rome ICTP awarded its 2018 Dirac Medal and Prize to three distinguished physicists - Subir Sachdev of Harvard University, Dam Thanh Son of the University of Chicago, and Xiao-Gang Wen of the Massachusetts Institute of Technology - for their independent contributions toward understanding novel phases in strongly interacting many-body systems, introducing original cross-disciplinary techniques. The Dirac Medal and Prize Ceremony will take place on Thursday 28 March 2019, starting at 14.00 hrs in the Budinich Lecture Hall. Three talks are scheduled, with an introduction by Prof. David Tong from the University of Cambridge, UK. - Prof. Dam Thanh Son "From fractional quantum Hall effect to field-theoretic dualities" Abstract: The fractional quantum Hall fluid is one of the most nontrivial strongly interacting fluids of nature. Many phenomena occurring in this fluid can be explained by postulating a new type of quasiparticle - the composite fermion. I will describe the new "Dirac composite fermion" theory, which has provided a simple solution to some long-standing puzzles and at the same time has stimulated the discovery of a large number of new dualities between quantum field theories in (2+1) dimensions. I will also describe physical consequences of the new theory Prof. Dam Thanh Son was born in Hanoi, Vietnam in 1969. He graduated from Moscow State University in 1991 and received his PhD in physics in 1995 from the Institute for Nuclear  Research in Moscow, Russia. He subsequently held postdoctoral appointments at the University of Washington and the Massachusetts Institute of Technology and faculty appointments at Columbia University and the University of Washington. In 2012 he moves to the University of Chicago where he is now a University Professor in the Department of Physics. He is a member of the U.S. National Academy of Sciences and the American Academy of Arts and Sciences. - Prof. Subir Sachdev "Strange metals and black holes" Abstract: The ‘strange metal’, a state of matter formed by electrons in many modern materials, including the compounds which exhibit high temperature superconductivity. In this state, electrons quantum entangle with each other and conduct electric current collectively (rather than one-by-one, as in an ordinary metal like copper). Quantum entanglement also has remarkable effects near the horizon of a black hole, leading to the Bekenstein-Hawking black hole entropy, and the Hawking temperature. Surprisingly, there is a deep connection between the nature of quantum entanglement in strange metals and black holes, and this has led to mutually beneficial insights. This connection is simply described by the Sachdev-Ye-Kitaev model, which leads to a common set of equations describing the quantum dynamics of certain strange metals and black holes. Sachdev was educated in Bangalore, India before attending MIT and Harvard where he obtained his PhD degree in theoretical physics. He held professional positions at Bell Labs (1985–1987) and at Yale University (1987–2005), where he was a Professor of Physics, before returning to Harvard where he is now the Herchel Smith Professor of Physics. He also holds a visiting position as the James Clerk Maxwell Chair in Theoretical Physics at the Perimeter Institute. He is a member of the National Academy of Sciences, fellow of the American Physical Society and has been awarded several honors, among them the Lorentz Chair, Instituut-Lorentz, Leiden University in 2012, Lars Onsager Prize from the American Physical Society and more recently the Dirac Medal from the ICTP in 2018. Sachdev delivered the Salam Distinguished Lecture series at ICTP in 2014. - Prof. Xiao-Gang Wen "Topological order and non-Abelian statistics" Abstract: Topological order describes a new kind of quantum matter (ie matter at zero temperature) beyond symmetry breaking. In this talk I will concentrate on one of the exotic properties of topological order in 2 space dimension: non-Abelian statistics, which is a generalization of the familiar Bose and Fermi statistics. It turns out that non-Abelian statistics allows us to us topologically ordered materials to perform topological quantum computations. Prof. Xiao-Gang Wen is a theoretical condensed matter physicist, recognized for his work on introducing the notion topological order (1989) and developing the theories of this new class of quantum states of matter. Since 2000, the study of topological states of matter slowly became a very active new field in condensed matter physics. Wen was born in Beijing, China. He went to the University of Science and Technology of China after the reopening of universities in China in 1977. Through T.D. Lee’s CUSPEA program, he obtained a chance to enter the graduate school of Princeton University in 1982, and earned a Ph.D degree in the field of superstring theory under Prof. Witten. During his postdoctoral period (1987-1989) in ITP, Santa Barbara, he started to pursue research in condensed matter physics. After a two-years stay in IAS, Princeton, he joined the faculty of department of Physics, MIT in 1991. ICTP's Dirac Medal, first awarded in 1985, is given in honor of P.A.M. Dirac, one of the greatest physicists of the 20th century and a staunch friend of ICTP. It is awarded annually on Dirac's birthday, 8 August, to scientists who have made significant contributions to theoretical physics. The events will be livestreamed from the ICTP website. Light refreshments will follow the event. All are welcome to participate.

Europe/Rome Abstract. Motivated by T Tbar deformation of a conformal field theory we compute holographic complexity for a black brane solution with a finite cutoff using complexity action proposal. In order to have a late time behavior consistent with Lloyd's bound one is forced to have a cutoff behind the horizon whose value is fixed by the boundary cutoff. Using this result we compute holographic complexity for two dimensional AdS solutions where we get expected late times linear growth. It is in contrast with the naively computation which is done without assuming the cutoff where the complexity approaches a constant at the late time. ICTP ICTP pio@ictp.it

Europe/Rome PLEASE NOTE UNUSUAL DAY FOR JOINT SP SEMINARS Understanding the nature and behaviour of excitations in quantum spin liquids, and in topological phases of matter in general, is of fundamental importance and has proven crucial for experimental detection and characterisation of candidate materials. Current theoretical and numerical techniques, however, have limited capabilities, especially when it comes to studying gapped excitations. In this talk, I will discuss a semiclassical numerical method, based on a large-$S$ path integral approach, to study systems whose spin liquid behaviour is underpinned by perturbative ring-exchange Hamiltonians. The method can readily access both thermodynamic and spectral properties. I will focus in particular on quantum spin ice and its photon and vison excitations. After benchmarking the method against existing results on photons, I will show how it can be used to characterise visons and their thermodynamic behaviour. We find that visons form a weak electrolyte -- in contrast to spinons in classical spin ice. That is, vison pairs are the dominant population at low temperatures. This is reflected in the behaviour of thermodynamic quantities, such as pinch point motifs in the relevant correlators. Moreover, visons appear to strongly hybridise with the photon background, a phenomenon that likely affects the way these quasiparticles may show up in inelastic response measurements. I will conclude with a brief discussion of the significance of our results and an outlook on further applications of our method. ICTP ICTP pio@ictp.it

Europe/Rome Some of the most sensitive and precise measurements to date are based on matterwave interferometry using freely falling atoms. Examples include ultra-high-precision measurements of inertia, gravity and rotation sensing [1-3]. Unfortunately, interaction time has to be very long in order to achieve very high sensitivities, resulting in interferometers often ten or even one hundred meters high or in the experiments having to be carried out in micro gravity on the space station[4–7]. Coherent matterwave guides and atomtronics will make possible highly compact devices having much extended interaction times and thus much increased sensitivity[8], which can be exploited both for fundamental and practical measurements. Here, we demonstrate [10] for the first time extremely smooth, coherence-preserving matterwave guides based on time-averaged adiabatic potentials (TAAP) [9]. We do so by guiding Bose-Einstein condensates (BEC) over macroscopic distances without affecting their internal coherence: We use a novel magnetic accelerator ring to accelerate BECs to more than 16x their velocity of sound. We transport the BECs in the TAAP over truly macroscopic distances (15 cm) whilst preserving their internal coherence. The BECs can also be released into the waveguide (Fig.1c) with barriers controllable down to 200 pK giving rise to new regimes of tunnelling and transport through mesoscopic channels. The high angular momentum of more than 40000 ħ per atom and high velocities raises interesting possibilities with respect to the higher Landau levels of quantum Hall states of atoms and open new perspectives in the study of superfluidity. Coherent matterwave guides will result in much longer measurement times (here > 4 s) and much increased sensitivity in highly compact devices. This will raise the spectre of compact, portable guided-atom interferometers for fundamental experiments and applications like gravity mapping or navigation. References: [1] Gustavson, T.

Europe/Rome Social dilemmas are ubiquitous in the world of human social interactions. The human ability to solve complex spatially and temporally extended social dilemmas is a key hallmark of our intelligence. Conversely, the cumulative nature of social tasks may provide an automatic path towards increasingly powerful cognitive abilities, under appropriate constraints. In this talk, I will argue for the ubiquity of social dilemmas from some simple principles, and show how complex spatially and temporally extended dilemmas may be solved by including appropriate inductive biases in state-of-the-art deep reinforcement learning agents. This approach simultaneously advances the fields of behavioural economics and artificial intelligence. I shall end with an outlook on how these fields might interact more closely in the future, both to improve our understanding of multi-agent dynamics in human society, and to construct generally intelligent artificial systems.

Europe/Rome Abstract. The main aim of this review talk is to present the state-of-the-art on the study of particle physics phenomena utilizing quantum computers and quantum simulators. In the first part of the seminar, I will introduce the concept of quantum simulation, following Feynmann's original vision, and discuss its applications in the field of ultracold atoms in optical lattices. Until few years ago, these applications had focused exclusively on models of relevance to condensed matter physics. I will present the key motivations that sparked a strong interest in quantum approaches to particle physics problems, in particular, in the context of (lattice) gauge theories. In the second part, I will discuss few examples on how trapped ions and cold atom gases can be used to emulate the real time dynamics of Abelian lattice gauge theories, and show how some of these approaches can be extended to certain non Abelian groups (U(N<11), SU(N<4)) utilizing alkaline-earth-like atoms. The first concrete experimental realizations in the context of the Schwinger mechanism will also be presented. Some introductory references to the topic written by HEP experts are: J.

Europe/Rome A 5-day series of lectures and computing practical exercises to help early career plasma physicists and spectroscopists develop an understanding of the techniques used to model and simulate radiative processes in plasmas. The properties of laboratory, industrial and astrophysical plasmas are determined by numerous atomic and molecular processes occurring under a wide range of physical conditions, generally far from equilibrium. The use of spectroscopic measurement in plasmas has been demonstrated to provide a powerful diagnostic technique, giving information on properties such as temperature, density, local plasma fields, electron energy distribution and so on, which is hard to obtain accurately by other means. The purpose of this School is to provide training for plasma physicists, plasma spectroscopists and astrophysicists for fusion and other applications by bringing together experts in experimental and theoretical plasma spectroscopy within the unique atmosphere and facilities of the ICTP. There is a particular focus on knowledge-transfer between researchers from developed and developing countries.

Europe/Rome The study of nonlinear systems continues to yield new and fascinating phenomena. Recently, a striking development has emerged in complex systems research: bringing together concepts from statistical and nonlinear physics allowed for the prediction and discovery of a novel effect, called the chimera state. Chimera states are a nice example of unexpected, counterintuitive dynamics where the interplay of synchronization, long-range interactions and pattern formation mechanisms are essential. The aim of the school is to review the progress in this field, where physics and applied mathematics strongly overlap with life sciences; find new interconnections and general analytic, numerical, and statistical approaches; and identify novel directions and cross-disciplinary applications. The targeted audience includes advanced undergraduate and PhD students, as well as post-doctoral fellows and junior researchers. Special attention will be devoted to the training of scientists from developing countries in line with the fundamental mission of the AS-ICTP. The workshop brings together a mix of world-leading experts in the field and young researchers to cover most important recent achievements in understanding of complex structures and the nature of synchrony in nonequilibrium systems.

Europe/Rome The main objective of the workshop is to enhance the capability of young scientists from developing countries to analyze and document scientific issues concerning regional climate modeling and projections, allowing them to provide stronger input to international programs such as the IPCC. As part of the CORDEX-CORE initiative, a set of regional climate change projections for continental regions worldwide are being completed with different RCMs, including the ICTP RegCM. These will be the basis for input into the upcoming IPCC report, which is based on published scientific articles. It is important that developing country scientists are directly involved in this process, and this workshop will provide a forum to exchange ideas on the analysis of the CORDEX-CORE experiments, and to plan for a series of scientific publications. The workshop will also include a special event on 30 years of Regional Climate Modeling. Specific topics include: Processes of regional climate change  Key issues in regional climate modeling (e.g. added value)  Distillation of robust information from ensembles of experiments  Uncertainty analysis  Tools for analysis of model output  Approaches to writing effective scientific paper ICTP ICTP pio@ictp.it

Europe/Rome The dynamics of pedestrian crowds share deep connections with the statistical physics of active matter. Pedestrians move following own will and objectives: this amounts in huge variability in the motion, observable even in diluted conditions. Despite such individual unpredictability, ensemble-level universal physical features emerge and encompass common and rare fluctuations of both the solo and the interacting dynamics. Reaching a quantitative understanding of these features is a major scientific challenge with deep societal impact, e.g. in the design of civil infrastructures or of crowd management measures. We investigate from observational experiments held in real-life settings (stations, festivals, museums) and in diluted conditions statistical features of pedestrian motion. We leverage on datasets including millions of trajectories acquired with and without external influencing stimuli (i.e., crowd control measures, like signage or visual cues), via home-made high-fidelity tracking systems. On this basis, we quantify the PDFs of individual velocity, position, body rotation and mutual-contact-avoidance "social" forces - possibly in dependence on stimuli. We propose an active-Brownian particle model of the dynamics based on Langevin-like equations statistically quantitative. This work is in collaboration with: J. Meeusen, C. Lee, A. Muntean, R.

Europe/Rome Universal Dynamics near Non-Thermal Fixed Points and Quantum Turbulence Abstract: Quenched or continuously driven quantum systems can show universal dynamics near non-thermal fixed points, generically in the form of scaling behaviour in space and time. Key aspects of the theory of non-thermal fixed points will be briefly summarized [1,2], as well as recent experimental results for quenched systems [3,4]. In a dilute Bose gas, universal scaling dynamics can be due to both, linear and non-linear excitations of the system. Considering scaling transport of excitations to larger wave numbers similar to an inverse cascade, the underlying excitations can be either irregular phase excitations or (quasi) topological defects exhibiting the implications for quantum turbulence. As an example, strongly anomalous scaling of inverse transport in a two-dimensional superfluid due to higher-order vortex annihilation will be discussed both, from the theoretical [5] and experimental point of view.

Europe/Rome The workshop will give an introduction to Global Navigation Satellite Systems (GNSS) operations and the impact of the ionosphere on them. It will concentrate on forecasting ionosphere conditions with focus on Total Electron Content. Its relevance for developing countries will be highlighted. Ionosphere Weather forecast, that depends strongly on the ability to forecast Space Weather events that reach the Earth, is increasingly needed for radiocommunications, satellite navigation and positioning operations. This is becoming as relevant as it is weather forecast in meteorology. The state of the art in forecasting ionosphere conditions is far behind the level of accuracy reached by weather forecast in the troposphere. Part of this limit is that the coupling of the ionosphere with the lower regions of the atmosphere is not adequately known, particularly in low latitudes where most of the developing countries are located.

Europe/Rome The Workshop is addressed to researchers from developing regions working on hydro-climate modelling with the aim to foster international research and educational projects on topics related to climate and hydrology, and will be a contribution to the G-WADI programme within the framework of UNESCO IHP VIII (2014-2021), Water Security: Responses to Local Regional and Global Challenges. Description: GEWEX is the lead project for WCRP’s Grand Challenge on Water Availability, which focuses on how fresh water availability will shift due to climate change in many food producing regions of the world. Fresh water availability can vary over in time due to reductions or increases in precipitation, evapotranspiration, runoff, ground water recharge or discharge, and snow melt. Climate extremes are one factor that can influence the intensity of precipitation in time, the snow melt timing and the exchange of water with land and, therefore, the storage of a region. All these make it imperative to better understand and predict precipitation variability and change. To this aim, the climate model community and, in particular, the regional climate community from one end is moving toward very high resolution simulation ensemble efforts down to the scale of the convection permitting resolution (1-3 km); and from the other end is working to implement fully coupled Earth System models to be able to understand the role of coupled water cycle and land atmosphere interactions in understanding local climate response. This will open new frontiers for the hydrological modeling community by bridging the spatial scale gap between regional climate models and impact models (hydrological models, ecosystem models, etc.); which will, in turn, affect the quality of the prediction of the hydrological cycle across several scales, from catchments to regional to global. Topics: • Precipitation measurements: what we can use to validate precipitation coming from the model output? • Ensemble of high resolution regional climate model outputs: how can those be used as input of a hydrological model? • Regional Earth System models: which is the role of the coupled water cycle? • Uncertainty in global and regional climate projections: how can this uncertainty be taken into account for hydro-climate simulation?

Europe/Rome Abstract: The Sato-Tate conjecture, originally stated for elliptic curves without complex multiplication, predicts the equidistribution of the normalized Frobenius traces with respect to the Sato-Tate measure, given by the pushforward of the Haar measure on SU(2). We would like to work on an analogous question for abelian varieties of dimension g > 1; the generalized Sato-Tate conjecture, introduced by Serre, which predicts the equidistribution on a certain compact Lie group: the Sato-Tate group. In 1966, Serre presented remarkable links between the Mumford-Tate group and the Sato-Tate group. Thus, the algebraic Sato-Tate group appears as an intermediate group between the Mumford-Tate group and the Sato-Tate group. Indeed, if the algebraic Sato-Tate conjecture holds for some particular abelian variety A of dimension g > 1, we can obtain the Sato-Tate group and try to deduce some new instances of the generalized Sato-Tate conjecture. The main goal of this talk is to present new results in the direction of the algebraic Sato-Tate conjecture, building on the previous work of Serre, Kedlaya and Banaszak. ICTP ICTP pio@ictp.it

Europe/Rome We discuss in detail the effects of Landau quantization on the quantum dynamics and statistical thermodynamics of Dirac-like materials in a high magnetic field. This discussion addresses the Group VI Dichalcogenides and Graphene in particular, but it also extends to the "Diced Lattice" as well as Silicene and Topological Insulators, etc. We also treat the role of nanostructures in Dirac-like materials, including quantum dots, quantum wires and a lattice of anti-dots. Starting with the derivation of the Landau-quantized "relativistic" Green's function for Dirac-like materials in position and momentum representations, as well as in eigenfunction representation, the associated energy spectrum in a high magnetic field is discussed. Furthermore, we develop the Green's functions for a model quantum dot in Graphene and a model quantum wire in the Group VI Dichalcogenides, examining their Landau quantized spectra as well. We also treat the case of a periodic lattice of anti-dots in the Dichalcogenides, tracing in detail the development of Landau minibands, with an explicit derivation of the Green's function for "relativistic" carriers in the lattice in a high magnetic field. In addition to the above-cited quantum dynamical stndies of "Dirac-like" materials (and spectra) in a high magnetic field we have also examined their statistical thermodynamics, developing the associated thermodynamic Green's function and spectral weight matrix subject to Landau quantization. With this we have determined the Helmholtz Free Energy, the Grand Partition Function as well as the ordinary Partition Function and the Entropy for the Dichalcogenides and the Diced Lattice in a high magnetic field explicitly; and have employed these to evaluate the magnetization of the "Dirac-like" materials in both degenerate and non degenerate statistical regimes, replete with de Haas-van Alphen oscillatory phenomenology (in the degenerate case).

Europe/Rome Abstract. Vector fields are insensitive to the rapid expansion of the primordial inflating universe due to their conformal coupling. However, they may couple to other light fields that are sensitive to the expansion and experience huge gravitational particle production, such as the complex scalar. In that case the vector field can develop large electric and magnetic field fluctuations induced by the gravitationaly enhanced charge fluctuations. I will present a computation of the one-loop corrections to the electric and magnetic field correlators of SQED in power-law inflation. One-loop corrections dwarf the tree-level result, and the slow-roll corrections very soon become large. ICTP ICTP pio@ictp.it

Europe/Rome Abstract. In this talk, I will discuss AdS3xS3xM4 backgrounds with pure NS-NS flux for M4=T4, K3 or S3xS1. I will show that the background with the lowest amount of NS-NS flux (`k=1') is dual to the large N limit of the symmetric product orbifold of M4. Showing this requires a description of string theory on AdS3xS3xM4 at k=1, where the standard RNS formalism breaks down. I will explain how the worldsheet theory can be consistently defined for k=1 by employing the hybrid formalism. The representation theory on the worldsheet for k=1 becomes far more restrictive than in the generic case, in particular all short string solutions and the continuum of long strings disappear, only the lowest energy long string solution is still allowed. I will also discuss the generalisation of the duality to higher flux, where the dual CFT can be described in terms of a Liouville theory. ICTP ICTP pio@ictp.it

Europe/Rome MOST OF KEY LECTURERS' SLIDES ARE AVAILABLE ONLINE. FINAL PROGRAMME IS AVAILABLE FOR DOWNLOAD (see link at foot or click here) - - - Energy and environmental issues are particularly challenging for the developing countries in general, both politically and economically. This may be due to the technological, cultural, and awareness gaps that exist in the general public in those countries with respect to the most developed countries. The impact of these gaps is mainly seen in the policies regarding global warming, the use of solar, wind, and hydrogen sources of energy, as well as the development of efficient energy storage technologies and capabilities. In 2012, the UN's SE4ALL issued a report which argues that no sustainable development can occur without sustainable energy. The Global Action Agenda defined by SE4ALL will require a critical mass of highly trained individuals within developing nations. Currently, the three major areas of energy-related research are energy conversion, energy saving (including efficiency) and energy storage, all of which will require significant capacity building within developing countries. Strengthening the scientific and technological knowledge base in these areas represents a realistic approach to reduce the dependence on foreign imported skills and resources. We believe that the understanding of the fundamental processes that are experimentally observed within materials at different scales can guide a very much needed approach of materials-by-design to improve efficiency and costs in several environment-friendly technologies. The School in Cartagena (Colombia) will provide an initial overview of recent experimental and theoretical developments and an in-depth treatment of some advanced computational methodologies that are used to address the problem of materials for energy and environmental applications. A multiscale view of the materials modeling, with electronic structure methods at its base, is of paramount importance to guide and understand experimental results. Such a view is becoming the dominant framework of investigation in condensed matter physics, materials science, biology, and nanoscience. In particular, methods such as Density Functional Theory are based on the almost exact solution of the Schrödinger equation for the electrons and allow for the description of the mechanical, vibrational, electrical, magnetic, and several other properties of solids with "chemical accuracy," without any empirical input. This is a rapidly evolving field, which also offers people in developing countries the opportunity to carry out cutting-edge theoretical research with relatively low financial investments in equipment. Our ultimate goal is to bring young scientists from those countries up to speed by providing them with the most recent knowledge about experimental developments as well as fundamental concepts coming from electronic structure research. This activity offers also networking opportunities for participants to facilitate carrying out state of the art theoretical research on clean-energy materials, back in their home institutions.

To capture the behaviors of exchange rate, the combination of Poisson jumps and generalized mixed fractional Brownian motion is introduced. To derive the pricing formula for some options, we firstly derive a generalized mixed fractional Girsanov theorem and some results regarding the quasi-conditional expectation that we will need for the rest of the paper. Then analytic pricing formulas for European currency option and exchange option are obtained using the equivalent martingale measure. Finally, through some numerical experiments and discussion we show that the GJMFBM model is different with the other previous ones. 14:30 - 14:45 - Un Gyong Ri (Kim Il Sung University) Presentation of Kim Il Sung University, Pyongyang, DPR Korea, and its educational programs in Mathematics ICTP ICTP pio@ictp.it

Europe/Rome In two seminal papers [1, 2] Onsager and Machlup introduced the celebrated theory of stochastic fluctuations for thermodynamic systems. Whereas their first contribution [1] proposes a variational principle that leads to a simple Langevin dynamics of first order in time, the second [2] extends this formalism to more complex systems that include inertia and memory effects via a second-order stochastic equation. I will present a higher-order generalization of the Onsager-Machlup theory and discuss its applications to equilibrium and nonequilibrium dynamics of currents. [1] L. Onsager and S. Machlup, Phys.

Europe/Rome Please note change of venue to Adriatico Guest House, Giambiagi Lecture Hall Abstract: Anomalous diffusion has been known since Richardson’s treatise on turbulent diffusion in 1926. Today the list of systems displaying anomalous dynamical behaviour is quite extensive and hosts, among others systems as charge carrier transport in amorphous semiconductors, collective slip diffusion on solid surface, transport in turbulent plasma and bacterial motion. In this talk I will focus on recent experimental observations of systems which exhibit a new anomalous behaviour with a linear growth of the mean square displacement, yet with a non-Gaussian distribution of increments. Based on the idea of diffusing diffusivitiy, I will illustrate a minimal model framework of diffusion processes with fluctuating diffusivity. In particular, I will demonstrate the equivalence of diffusing diffusivity processes with a superstatistical approach with a distribution of diffusivities, at times shorther than the diffusivity correlation time. At longer times, a crossover to a Gaussian distribution with an effective diffusivity emerges. Specifically, I will establish a subordination picture of Brownian yet not Gaussian diffusion processes, which can be used for a wide class of diffusivity fluctuation statistics. In the last part of the talk, I will show how a simple polymerization process provides a suitable set-up to bridge the diffusing diffusivity approach with a microscopic description.

Europe/Rome Sensors are an integral part of any instrumentation, mechanical assembly, automobile engineering, heavy engineering, drug-delivery vehicles, national surveillance gadgets or any electromagnetic application unit, such as antennas and communication electronics. A need for smart, adaptive, miniaturized, extremely sensitive, selective and rapid sensor is always on anvil. Nanomaterials are offering promising options to improve the conventional sensors and to develop advanced sensors which would be adaptive, faster, selective and more precise. Nanotechnology has been dominating applied research frontiers for more than a decade now. The research has an emphasis on exploring novel materials with exotic properties, which are attributed to their nano-size-regimes. Typically explored examples are metals, oxides and chalcogenides, in their pure and composite forms. Through this presentation a brief outline on the progress of science and technology, in the domain of sensors will be given. Frequency detections; low-field and frequency (electric and magnetic fields and ultra-low-frequency signals), high frequency (radio frequencies in Radar range) detections will be discussed. Biosensors being developed for disease diagnostics and smart drug delivery vehicles would be also elaborated in this presentation. Various approaches used in the investigators laboratory would be elaborated; namely, the optical fiber approach, metamaterial approach and conventional resistive approach. The relationships of the obtained properties would be associated with the physics and chemistry at nano-level and their energy dynamics for sensing a particular physical parameter.

The gold-fullerene systems constituting alkane thiol capped gold nanoparticle and pristine fullerene in explicit water have been simulated and studied. The van der Waals interactions between the thiol capped gold nanoparticle and fullerene have facilitated the formation of gold-fullerene nanocomposite. The active terminal methyl (hydrophobic) and hydroxy (hydrophilic) groups have influenced the time of formation of self-assembly, stability, conformation and dynamics of the thiol chains, and specific heat capacity of the gold-fullerene nanocomposite. The variation observed in the structure, specific heat capacity and wetting behaviour of gold-fullerene nanocomposite with respect to the terminal functional groups suggests the possiblity of tuning the functions of gold-fullerene nanocomposite by changing the terminal functional groups.

Europe/Rome Abstract: It has long been known that the distribution of the prime numbers is intimately connected to the distribution of the zeros of the Riemann zeta-function. Much information can be obtained from the horizontal distribution of zeros, but finer information about primes seems to be connected to the vertical distribution of zeros. By studying the pair correlation of the normalized spacing between the zeros, Montgomery was lead to the conjecture that the statistics of vertical spacings should follow the GUE distribution from random matrix theory. I will survey some of the methods used to prove the existence of large and small gaps between zeros of the zeta function, highlighting the state-of-the-art and the limitations. I will also discuss some recent joint work (with Hung Bui and Dan Goldston) were we prove the existence of small gaps between distinct zeros of the zeta function, a result that previous methods seem incapable of establishing.

Europe/Rome In 1959 Mark Kac introduced a simple model for the evolution of a gas of hard spheres undergoing elastic collisions. The main simplification consisted in replacing deterministic collisions with random Poisson distributed collisions. It is possible to obtain many interesting results for this simplified dynamics, like estimates on the rate of convergence to equilibrium and validity of the Boltzmann equation. The price paid is that this system has no space structure. I will review some classical results on the Kac model and report on an attempt to reintroduce some form of space structure and non-equilibrium evolution in a way that preserve the mathematical tractability of the system.

Europe/Rome Antiferromagnetically interacting quantum spins on kagome lattice form a highly frustrated system. While the spin-1/2 kagome problem continues to be debated, it has been recently shown (by us and few others) that the spin-1 kagome Heisenberg antiferromagnet realises a spontaneously trimerized quantum paramagnetic ground state. We further look into the dynamics of this trimerization through a spin-1/2 model realised in a family of organic salts and first studied by Hida. In a certain strong coupling limit, the Hida model becomes the spin-1 kagome Heisenberg model, while in the opposite limit, it describes a system of weakly coupled antiferromagnetic spin-1/2 hexagons. We study the ground state of the Hida model from this weak to strong coupling limit, and systematically understand the trimerization as it occurs for the spin-1 kagome antiferromagnet. We also discuss its experimental signatures by calculating the spin structure factor. ICTP ICTP pio@ictp.it

Europe/Rome We present solutions of the Einstein equations that extend the static Schwarzschild solution in empty space into regions of non-zero energy density $\rho$ and radial pressure $p= w \rho$, where $w$ is a constant equation of state parameter. For simplicity we focus mainly on solutions with constant $\rho$. For $w=0$ we find solutions both with and without a singularity at the origin. Possible applications to galaxies are considered, where we find enhanced velocity rotation curves towards the edge of a galaxy. We propose that our explicit non-singular solution with $w=-1$ describes the interior of a black hole, which is a form of vacuum energy. We verify that its entropy is consistent with the Bekenstein-Hawking entropy, if one assumes the Hawking temperature. We further suggest that this idea can perhaps be applied to the dark energy of the observable universe, if one views the latter as arising from black holes as pockets of vacuum energy. We estimate the average density of such a dark energy to be $\rhobar_\Lambda \approx 10^{-30} g/{\rm cm}^3$. SISSA, Via Bonomea 265 ICTP pio@ictp.it

Europe/Rome Abstract: Maximal operators are central objects of study in harmonic analysis. The most classical example is the Hardy-Littlewood maximal operator (in both its centered and uncentered form) but there are also other interesting ones, for instance the ones associated to a convolution with a smooth kernel. In this introductory talk we will introduce the sub-area of harmonic analysis that studies how the variation of a maximal function behaves with respect to the initial data. We will discuss the classical results in this topic (most of them dealing with the one dimensional case) and later we will talk about some recent results that deal with the higher dimensional case when restricted to radial data. Also we will show some analogues of these problems when the domain of the functions are non-trivial manifolds, in particular a recent result on the d-sphere. ICTP ICTP pio@ictp.it

Europe/Rome There is a great interest in understanding the optimal features of the performance of finite-time thermal machines. Efficiency at maximum power and the coefficient of performance at maximum cooling power, are some of the useful criteria that are studied. Universal features of these quantities are observed in many different models, such as those based on endoreversibility assumption, low-dissipation assumption, stochastic heat engines, and even quasi-static models. We discuss a model of heat engine within the framework of linear irreversible thermodynamics. The model runs in a finite cycle time. We show that the model can be mapped to a low-dissipation model whereby the entropy generated in a heat-exchange step, is inversely proportional to the duration of the process. The optimal features of the efficiency will be discussed. ICTP ICTP pio@ictp.it

Europe/Rome We propose a microscopic magneto-electric model in which the coupling between spins and electric dipoles is mediated by lattice distortions. The magnetic sector is described by a spin S=1/2 Heisenberg model coupled directly to the lattice via a standard spin-Peierls term and indirectly to the electric dipole variables via the distortion of the surrounding electronic clouds. Electric dipoles are described by Ising variables for simplicity, as tunneling quantum effects do not substantially modify the results. We show that the effective magneto-electric coupling which arises due the interconnecting lattice deformations is quite effcient in one-dimensional systems. More precisely, we show using bosonization and extensive DMRG numerical simulations that increasing the magnetic field above the spin Peierls gap, a massive polarization switch-off occurs due to the proliferation of soliton pairs. We also analyze the effect of an external electric field E when the magnetic system is in a gapped (plateau) phase and show that the magnetization can be electrically switched between clearly distint values. We compare these findings with similar effects that have been recently observed in different materials. More general quasi-one-dimensional models and two-dimensional systems are also discussed. We finally propose a possible device (MERAM) based on materials with the behavior described by the present model. ICTP ICTP pio@ictp.it

Europe/Rome I will address the emergence of cooperative effects in driven-dissipative many-body quantum systems out of equilibrium, such as superradiant light emission, spin squeezing, phase transitions, and dark states [1-2]. The use of permutational symmetry allows one to efficiently solve the Lindblad dynamics with an exponential reduction in computational resources even accounting for local homogeneous dissipation channels [2]. Using the formalism of Dicke states, it is also possible to extend the study of the driven-dissipative dynamics also to the so-called “ultrastrong” coupling regime of light-matter interaction [2,3]. We crafted a tool in the form of an open-source software, the permutational invariant quantum solver (PIQS) and integrated it in the Quantum Toolbox in Python, QuTiP (www.qutip.org) [4], making it available to the research community for future investigations [5].

Europe/Rome Cells sense and respond to topographical, chemical, and mechanical characteristics of their substrate. Engineered substrates are increasingly being developed that exploit these physical attributes to direct cell responses and therefore control cell behavior toward desired applications. There are very few methods available for robust and accurate modeling that can predict cell deformations and force propagations along the cell media. Here, we developed a unifying computational framework to create a multi-component cell model to predict cell behavior. The model which we call it “virtual cell model” has the capability to predict changes in whole cell and its nucleus characteristics [1]. The changes in shape and elongation of the membranes, force distribution, and chromatin contact map are predicted on a range of substrates. Modeling data are correlated with cell culture experimental outcomes in order to confirm the applicability of the model and demonstrating the ability to reflect the qualitative behavior of mesenchymal stem cells [1,2]. Here we show controlled cell migration is possible just by proper design of the substrate. References: [1] ACS Nano, 2017, 11 (9), pp 9084–9092, DOI: 10.1021/acsnano.7b03732 [2] Adv. Funct.

Europe/Rome Abstract: Nested Hilbert schemes of points and curves on smooth projective surfaces carry interesting quantities for both geometry and physics. Their virtual fundamental classes have been shown to recover both the virtual classes of SW and reduced stable pair theories, while their obstruction theories can be used to obtain information about VW and reduced DT invariants. We show that the effective SUSY theory of a certain surface defect gives rise to a quiver GLSM which, in a particular case, models punctual nested Hilbert schemes on the complex plane. We will show how the partition function of such a theory naturally computes certain virtual invariants of these moduli spaces and how these results relate to a conjecture of Hausel, Letellier and Rodriguez-Villegas about the cohomology of character varieties.

Europe/Rome The school will focus on the organization of convection in the tropics and its possible implications for climate sensitivity. Some idealized convection permitting models show spontaneous clustering of convection can occur, drying the tropical atmosphere and increasing infrared emission to space. This effect could imply a strong negative feedback on the climate that may be missing or poorly represented in global climate models. However, there is open debate concerning the mechanisms involved, the implications for climate, the evidence in the observations, the role of shallow clouds and convection, the spatial scales of instability and the connection of this idealized aggregation to common examples of tropical organization such as the Madden Julian Oscillation or tropical cyclones. The event will consist of a one-week school, with some introductory lectures and the chance to work with observations and model output to address questions related to convective organization. In the second week, participants will benefit from open debate with over 20 of the world’s leading scientists in the field. Experts will work with student groups to summarize the debates in position papers, including results from the first week’s exercises.

Europe/Rome A special event will take place on Monday 8 July 2019 starting at 16.00 hrs in the Budinich Lecture Hall at ICTP. The following talks on hot topics of climate change, of approx 20 minutes each, are planned. Sandrine Bony, LMD, France: Clouds in the climate system, why so much uncertainty? Kerry Emanuel, MIT, USA: Will our weather extremes become even more extreme? Bjorn Stevens, Max Planck Institute for Meteorology (MPIM), Germany: "Beyond Global Warming". Questions can be submitted to a dedicated link to build the discussion after the talks. The event will be livestreamed from the ICTP website. All are most welcome to participate. Information on the speakers and abstracts: Sandrine Bony is a CNRS Director of Research in Paris, France. Her main research interest is advancing understanding of the role of clouds and cloud processes in climate sensitivity and in the large-scale circulation of the atmosphere, using a combination of modeling, observational and conceptual approaches. She is presently co-organising a large-scale field experiment that will take place in 2020 over the tropical Atlantic near Barbados. Kerry Emanuel is the Cecil and Ida Green professor of atmospheric science at the Massachusetts Institute of Technology in the USA. His research speciality is hurricane physics and he was the first to investigate how long-term climate change might affect hurricane activity, an issue that continues to occupy him today. His interests also include cumulus convection, and advanced methods of sampling the atmosphere in aid of numerical weather prediction. Bjorn Stevens is a director at the Max-Planck-Institute for Meteorology in Hamburg, Germany. His research blends modeling, theory and field work to help articulate the role of aerosols, clouds and atmospheric convection in the climate system with pioneering contributions to both understanding and modelling of mixing and microphysical processes and their impact on the structure and organization of clouds. ABSTRACTS: SANDRINE BONY: Clouds in the climate system, why so much uncertainty? Clouds are often quoted as 'the largest source of uncertainty in climate change'. Why? Some of the reasons why clouds are so important for climate and climate change will be reviewed. In particular, it will be shown how, by affecting the radiative exchanges between the Earth and space, clouds can influence the magnitude of global warming and the regional distribution of wet and dry areas around the world. Areas of research which might improve our understanding and prediction of the role of clouds in climate change will be discussed. BJORN STEVENS: Beyond Global Warming The outlines of global warming are clear. Earth has warmed by about 1ºC relative to a baseline in the late 19th century. Barring surprises it will warm by an additional 1ºC over the next half century. Beyond the general outline of this warming trend, and its causes, the science is anything but settled. In this talk I will look into the crystal ball of worlds unknown, explain why doing so is important, and outline new approaches that may help address the challenges a warming world poses for climate scientists. KERRY EMANUEL: Will our weather extremes become even more extreme? I will review the theoretical bases for the idea that tropical cyclones will become more intense and produce more rain as temperatures rise, and present some new results pertaining to Hurricane Maria in 2017. Of particular concern for Italy, we will also review what is known about Mediterranean hurricanes (or “Medicanes”) and how they might respond to climate change, with an extension to polar lows if there is time. Finally, the relationship between extratropical cyclones and climate will be discussed. ICTP ICTP pio@ictp.it

Europe/Rome Point process modeling has been widely used as a powerful statistical tool in describing, investigating, and forecasting social, economic, and natural phenomena. Especially, the Hawkes-type models describe the interaction between discrete events: each event, no matter whether it is a background event or an excited event, influences the occurrence of the future events, through triggering (“encouraging” of) events, according to some probability rules. Since the Hawkes models can be used to investigate the interaction between discrete events, they became more and more popular in many fields, such as crime data analysis, economics, and seismology. In this talk, using the ETAS model for earthquake occurrences and a nonparametric Hawkes model for crime data as the illustrative examples, I will explain the methods of stochastic declustering and stochastic reconstruction. Stochastic declustering helps us to realize the family-tree structure among the events in a stochastic manner. Stochastic reconstruction is a technique for model diagnostics and later is generalized to a nonparametric method for estimating the branching characteristics for more general branch process models, by incorporating other smoothing techniques. The stochastic reconstruction method can be validated through the viewpoints of martingale theory. I will show its powers by the examples of extending two existing Hawkes-type models in earthquakes and crimes data analysis. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: We study diffusion and mixing in different fluid dynamics models, mainly related to incompressible flows. In this setting, mixing is a purely advective effect which causes a transfer of energy to high frequencies. Mixing acts to enhance the dissipative forces, giving rise to what we refer to as enhanced dissipation. We understand by this the identification of a decay time-scale, which is faster than the purely diffusive one. We will give a general quantitative criterion that links mixing rates (in terms of decay of negative Sobolev norms) to enhanced dissipation time-scales. Applications include passive scalar evolution in both planar and radial settings, fractional diffusion, linearized two-dimensional Navier-Stokes equations, and even simple examples in kinetic theory.

Europe/Rome Abstract: One of the oldest problem in geometric analysis and in the calculus of variations consists in finding a surface of leat area surface spannend by a given smooth curve $\gamma$. The approach of Douglas and Rad ensures, for each prescribed genus, the existence of a surface minimizing the area among all the ones with smaller genus. On the other hand, after the seminal work of Federer and Fleming, it is always possible to find a mass minimizing current spanned by $\gamma$. When the Federer fleming solution is smooth (up to the boundary) , it naturally coincides with the Dougals Rado solution. In co-dimension one, thanks to the seminal work of De Giorgi and Hardt-Simon, this is indeed the case. In higher co-dimension the question is not yet completely understood and new phenomena might appear. In this talk, after surveying the known results, I will present the construction of a smooth curve in a 4 dimensional Riemannian manifold which spans an area minimizing surface with infinite genus. This is based on a joint work with C. De Lellis and J. Hirsch. ICTP ICTP pio@ictp.it

Europe/Rome We report the experimental evidence of the existence of a random strange attractor in a fully developed turbulent swirling ow. By defining a global observable which tracks the asymmetry in the of angular momentum imparted to the ow, we can reconstruct the associated turbulent attractor and then follow its route towards chaos. We further show that the experimental attractor can be modeled by stochastic Duffing equations, that match the quantitative properties of the experimental flow, namely, the number of quasi-stationary states and transition rates among them, the effective dimensions, and the continuity of the Lyapunov exponents. Such properties can be recovered neither using deterministic models nor using stochastic differential equations based on effective potentials obtained by inverting the probability distributions of the experimental global observables. A random map extracted from the experimental time series of the turbulent ow exhibits qualitatively same stochastic bifurcation structure as the experimentally observed transitions. Our findings open the way to low-dimensional dynamical system modeling of systems featuring a large number of degrees of freedom and multiple quasi-stationary states. ICTP ICTP pio@ictp.it

Europe/Rome The Eastern Africa Universities Mathematics Programme (EAUMP) courtesy of the International Science Programme (ISP) of Sweden; jointly with ICTP, Trieste, Italy; Sida, CIMPA, DAAD, LMS/AMMSI, COMPOSITIO is organizing a three weeks summer School on Algebraic Topology and its Applications to be held at Makerere University, Kampala, Uganda from 15th July to 30th July, 2019. It is intended that the School will take the audience comprising young academic staff members and advanced graduate students (M.Sc, Ph.D and Postdoctoral Students) of Mathematics from the Eastern African region and beyond. The school is the next one in a series of schools organized under the Eastern African Universities Mathematics Programme (EAUMP). The most recent EAUMP schools were organized in 2015 at Makerere University, Uganda, on Experimental Pure Mathematics; in 2016 at the University of Rwanda on Number Theory; in 2017 at the University of Nairobi on Modern Functional Analysis; and in 2018 at the University of Dar es Salaam on Homological methods in Algebra and Geometry. All the schools are within one of the main aims of EAUMP which is to improve the pure mathematics in the region. The member Universities of the EAUMP are University of Dar es Salaam, Tanzania; University of Nairobi, Kenya; University of Zambia, Zambia; Makerere University, Uganda; University of Rwanda, Rwanda. GOALS OF THE SCHOOL To introduce participants to current trends in Algebraic Topology and its applications, including knot theory and Topological Data Science, and provide research topics for masters and PhD studies. To provide a forum for African mathematicians to interact, exchange ideas and initiate collaborations. Identify talented students for possible PhD programs. To produce digital lecture material for dissemination, which contributes to the training of master students in the Eastern Africa region. STURCTURE AND PROGRAMME As in the years 2013-2017, participants will be asked to submit mini-projects on the material studied at the School, with the best submissions receiving prizes/awards. They will work on their projects after the end of the School and will submit them during the third week of the school. Here is the detailed course plan for the School. Week 1: Introductory courses Course 1: Introductory Topology Lecturer: Venuste Nyagahakwa (University of Rwanda) Description: This course will introduce the basic ideas of topology, starting with an abstract definition of topological space, and treating many examples. Course 2: The Fundamental Group Lecturer: Jean-Baptiste Gatsinzi (Botswana Institute of Science and Technology) Description: The fundamental group is a basic but key algebraic invariant of a topological space. This course will define this group and give some interesting examples of how to compute it. Course 3: Introduction to knot theory Lecturer: Balazs Szendroi (University of Oxford) Description: A knot is a tangled piece of rope in the three dimensional space, with the two loose ends glued together. Knot theory asks questions such as: can this knot be untangled by continuously deforming the rope? Are there ways to tell two knots apart? This course will discuss these motivating questions and present some ideas how to solve them. Week 2: Advanced courses Course 3: Manifolds Lecturer: Claudia Scheimbauer (NTNU, Trondheim) Description: Manifolds provide a very interesting class of examples of topological spaces, of great interest in applications to geometry, physics and elsewhere. This course will introduce this notion with many examples, mainly from dimensions 1, 2 and 3. Course 4: Topological Data Analysis Lecturer: Ulrike Tillmann (University of Oxford) Description: Topological data analysis is a recent and fast-growing field providing a set of new topological and geometric tools to infer global features from complex data. This course will give an introduction to this circle of ideas. SCHOOL PARTICIPATION Online application form is available at http://indico.ictp.it/event/8699/, and will close on 28th April, 2019.

Europe/Rome Active fluids are a novel class of non-equilibrium complex fluids with examples across a wide range of biological and physical systems such as flocking animals, swarming microorganisms, vibrated granular rods, and suspensions of synthetic colloidal swimmers. Different from familiar non-equilibrium systems where free energy is injected from boundaries, an active fluid is a dispersion of large numbers of self-propelled units, which convert the ambient/internal free energy and maintain non-equilibrium steady states at microscopic scales. Due to this distinct feature, active fluids exhibit fascinating and unusual behaviors unseen in conventional complex fluids. Here, combining high-speed confocal microscopy, holographic imaging, rheological measurements and biochemical engineering, we experimentally investigate the dynamics of active fluids. In particular, we use E. coli suspensions as our model system and illustrate three unique properties of active fluids, i.e., (i) abnormal rheology, (ii) enhanced diffusion of passive tracers and (iii) emergence of collective swarming. Using fluid mechanics and statistical mechanics tools, we develop a quantitative understanding of these interesting behaviors. Our study illustrates the general organizing principles of active fluids that can be exploited for designing “smart” fluids with controllable fluid properties. Our results also shed new light on fundamental transport processes in microbiological systems. SISSA, Via Bonomea 265 ICTP pio@ictp.it

Europe/Rome A century ago Einstein developed a theory of diffusion that is based on the assumption of stochasticity for a Brownian particle. On a molecular level, however, diffusion is generated by Newton’s deterministic equations of motion, which typically are highly nonlinear. In my talk I will review, in a very tutorial manner, a theoretical approach that derives diffusion from first principles by starting from microscopic deterministic chaos. Simple models ranging from a deterministic random walk on the line to chaotic diffusion in potentials on periodic lattices will be studied analytically and by computer simulations. Surprisingly, the diffusion coefficients of these models turn out to be highly irregular, fractal functions of physical control parameters while simple random walk theory predicts monotonicity. This is due to memory in the deterministic single-particle dynamics. I will argue that this phenomenon should be seen in experiments on small systems, such as molecular diffusion in zeolite nanopores and diffusion of electrons in artificial graphene.

Europe/Rome Stochastic thermodynamics provides a consistent description of a wide class of Langevin systems, but the Markov assumption is often essential. While some non-Markovian systems have been studied in great detail, the important case of feedback control with a discrete delay is still insufficiently understood [1,2]. The thermodynamical description of nonlinear delayed systems turns out to be particularly challenging. In this talk, I will consider the paradigmatic example of a Brownian particle in a doublewell potential subject to time-delayed feedback in its non-equilibrium steady state. We use different strategies to tackle the technical challenges arising due to the delay, such as closure schemes for the infinite Fokker-Planck hierarchy [3,4] and a Markovian embedding technique [4,5]. We find an unavoidable heat flow induced by the control (even in the absence of any additional driving), i.e., the feedback inevitably cools down or heats up the system [1]. Interestingly, the heat flow is enhanced in the limit of small delay times, which is a phenomenon related to entropy pumping. We further compute the total entropy production of the super system, consisting of the particle plus the memory of the controller. By varying the information capacity of the memory device, we can consider different Gamma-distributed delays, including the limit of an infinitely sharp (delta-peaked) kernel, i. e., discrete delay. We identify an entropic contribution due to the memory, which is a consequence of the unidirectional information flow induced by the feedback-controller. This contribution diverges in the case of error-free measurement, as well as in the case of a perfectly sharp (delta-peaked) time delay. [1] Loos & Klapp, Sci.

Europe/Rome Recurrent neural networks have been recently introduced to predict the behavior of chaotic systems. Surprisingly, they provide reliable forecasts up to the predictability limit without knowing the underlying equations of the systems. Here we focus on the predictability of rare trajectories leading to extreme events. We focus on different chaotic systems, ranging from toy models of the atmospheric dynamics, up to the re-forecast of sea-level pressure and temperature fields issued by ERA Interim and NCEP reanalysis datasets. Our results show that: i) the machine learning techniques can make reliable weather forecasts of global atmospheric fields up to 48-72h with a time step of 3-6h ii) long time forecasts do not diverge, they produce reliable climatology of the sea-level pressure and temperature fields iii) we can evaluate the coherence of extreme events generated via the machine learning with respect to the observed ones.

Europe/Rome Abstract. Future large scale structure surveys are designed to study the nature of the dark side of the universe and the physics of the initial condition of the cosmos. In this context, the understanding of the distribution of structures of the cosmic web: dark matte halos, cosmic filaments and large scale voids in one hand and their clustering and connection with the luminous matter known as bias parameter, on the other hand are all valuable probes of beyond standard model of cosmology. In this talk, I will introduce the excursion set theory (EST) of nonlinear structure formation and the non-Markov solutions of first up-crossing in EST context which opens a new venue to study the distribution of dark matter halos and the bias parameter in more realistic cases. Also I will introduce the excursion set theory of saddle points as a new framework for studying cosmic filaments. Finally, I will discuss that how the EST framework can address the void phenomena in the context of uLCDM model which is introduced to address the H_0 tension. ICTP ICTP pio@ictp.it

Europe/Rome For ICTP-SAIFR school website click here The Advanced School and Workshop will bring together scientists and students for presenting and discussing the progress in research on the American monsoons and their role in the global monsoon system, and for planning future activities. The American monsoons are important components of the global monsoon system. A very high percentage of the annual precipitation over most of South America occurs during the summer monsoon, including subtropical regions. The economy, agriculture, water and energy resources and, consequently, the livelihoods of the great majority of South America population are heavily dependent on the summer monsoon. Also the North American monsoon provides crucial water resources for Mexico, Central American countries, several island nations in the Caribbean and parts of the southwest USA. Predicting the intensity of American monsoon rainfall is not only a regional challenge, but is also relevant in the framework of a global sub-seasonal to seasonal forecasting system. The Advanced School and Workshop are fostered by the Working Group on American Monsoons, one of the regional monsoons working groups established under the coordination of the CLIVAR/GEWEX Monsoons Panel. Topics to be covered include: Global context, main features, life cycle of the American monsoons; Variability on diurnal, mesoscale and synoptic time scales; sub-seasonal to seasonal variability; Variability on interannual and decadal/interdecadal time scales; modulation of extreme events by climate variability; longer term variability and climate change; Predictability and prediction (weather, sub-seasonal, seasonal and longer lead times); modelling studies; Impacts on society; future challenges; plans for observational studies, diagnostic analyses, and modelling activities. Discussions on future collaboration. Participation The targeted audience includes scientists and advanced undergraduate and graduate students, interested in the American monsoons and their role in the global monsoon system.

Europe/Rome Abstract. In the simplest scenarios of the cosmic inflation the universe, at the very onset of its evolution, is almost empty filled with only a single scalar field, the inflaton, whose background energy density is responsible for the nearly exponential expansion of the universe and its quantum fluctuations, once stretched beyond the horizon scale, serve as the primordial seeds of clumpy universe we see today. Although the predictions of this vanilla model is well compatible with current data ranging from CMB to LSS, there has been a continuing endeavour to study the consequence of presence of extra fields other than inflaton on those observables. In this talk, I am going to talk about possible footprints of light extra degrees of freedom during inflation on the primordial power spectrum of the curvature perturbations. ICTP ICTP pio@ictp.it

Europe/Rome Abstract: B-branes on Calabi-Yau (CY) X manifolds are in 1-1 correspondence with objects in the derived category of coherent sheaves. B-branes on Gauged Linear Sigma Models (GLSM) can be roughly interpreted as objects of the derived category of a CY stack. This interpretation can be used to generate equivalences between various categories associated to geometric and nongeometric phases of a CY. I will introduce these concepts and present some results for the case when the stack is not CY (physically, this means the GLSM is anomalous), that can be derived from physics. In particular I will explain how the equivalences between categories associated to phases are modified and comment on some consequence on K-theory using as a guide the example of Hirzebruch-Jung resolutions of cyclic surface singularities.

Europe/Rome Abstract. We propose quantum states for Little String Theories (LSTs) arising from M5 branes probing A- and D-type singularities. This extends Witten's picture of M5 brane partition functions as theta functions to this more general setup. Compactifying the world-volume of the five-branes on a two-torus, we find that the corresponding theta functions are sections of line bundles over complex 4-tori. This formalism allows us to derive Seiberg-Witten curves for the resulting four-dimensional theories. Along the way, we prove a duality for LSTs observed by Iqbal, Hohenegger and Rey.

Europe/Rome Biosketch: Prof. Liliana Arrachea from the International Center for Advanced Studies, Universidad Nacional de San Martín in Argentina obtained her PhD from Universidad Nacional de La Plata, Argentina in 1995. Following this, her research positions have included Alexander von Humboldt fellow at FU-Berlin and Max-Planck Institut, Germany, Postdoctoral researcher at SISSA, Trieste, and Ramón y Cajal Researcher at University of Zaragoza. She has been a Researcher of CONICET Argentina since 1999, an Associate Professor from University of Buenos Aires since 2007 (on leave since 2016), and Full Professor at University of San Martín, Argentina since 2016. In addition, Prof. Arrachea was appointed Guggenheim Fellow 2010, and Simons Associate at ICTP-Trieste since 2015, and Georg-Forster Alexander-von-Humboldt Research Award 2016. Prof. Arrachea spends periods comprising several months at a time as Invited Professor at PUC-Rio de Janeiro, Université Paris 7, and Boston University. Abstract: Boosting the efficiency for the conversion of electrical and thermal energy at finite power is motivating an intense research activity, not only in the areas of material science and applied physics but also in experimental and theoretical areas of statistical mechanics and condensed matter physics. Efforts are concentrated in developing new materials and devices as well as on analyzing different operational conditions. In the latter direction, taking advantage of the quantum effects is one of the most interesting avenues. Nanoscale devices and topological materials provide an excellent scenario to explore these properties. In this talk, I will present a general overview on the field. I will also present some examples and discuss some fundamental theoretical aspects. The talk will take place on 28 August 2019 at 16.30 in the Euler Lecture Hall @ ICTP.

Through Fourier Analysis we will make a reduction to study two different situations, in one of them we will appeal to the Bourgain best constant argument and in the other we will use a nice incidence result established recently 15:30 - 16:00 break 16:00 - 17:00 Mariana Smit Vega Garcia (Western Washington University) Title: Free boundary problems Abstract: The study of one of the most renowned examples of free boundary problems, the classical obstacle problem, began in the 60’s with the pioneering works of G. Stampacchia, H. Lewy and J. L. Lions. During the past five decades, it has led to beautiful and deep developments in the calculus of variations and geometric partial differential equations. One of its crowning achievements has been the development, due to L. Caffarelli, of the theory of free boundaries. Nowadays the obstacle problem continues to offer many challenges and its study is as active as ever. In this talk, I will overview the obstacle problem and describe a few methods used to tackle two fundamental questions: what is the optimal regularity of the solution, and what can be said about the free boundary. This is based on joint works with Mark Allen, Nicola Garofalo & Arshak Petrosyan. ICTP ICTP pio@ictp.it

Europe/Rome Timothy Beers is the Grace-Rupley Professor of Physics at the University of Notre Dame, and a co-PI in the Physics Frontier Center JINA-CEE (Joint Institute for Nuclear Astrophysics – Center for the Evolution of the Elements), funded by the US National Science Foundation. He is a former director of the US Kitt Peak National Observatory, and spent 25 years working as a Professor in Physics & Astronomy at Michigan State University. Beers is interested in the origin and evolution of the elements in the Universe, and the assembly of large spiral galaxies such as the Milky Way, a field now referred to as Galactic Archaeology. For decades, Professor Beers has designed and executed large-scale surveys of stars in the Milky Way, efficiently sifting through literally millions of individual stars in order to find those objects that have recorded the chemical history of the Universe in their atmospheres. His work has led to the identification of a subset of the so-called carbon-enhanced metal-poor (CEMP) stars that exhibit a characteristic light-element signature (enhanced C, N, O, Na, Si, Mg), now recognized to be due to nucleosynthesis processes associated with the very first stars born in the Universe. Presently he is conducting a survey for so-called r-process-enhanced stars, which are metal-poor stars that exhibit over-abundances of elements produced by the rapid neutron-capture process, and place strong constraints on the origin of over half of the elements beyond iron in the Periodic Table. Abstract: In this, the 150th Anniversary year of Mendeleyev’s Periodic Table, astronomers have pieced together plausible origin stories for most of the elements formed in nature. From the breakthrough observations of Paul Merrill (1952), which first demonstrated that essentially all elements beyond H and He were formed in stars, to the discovery of the astrophysical origin of the rapid neutron-capture elements in binary neutron star mergers (2017), I present a summary of our modern understanding of this fascinating history. I also highlight a number of remaining questions, and how astronomers and physicists are working to fill in our gaps in knowledge. The talk will be livestreamed from the ICTP website.

Europe/Rome It has been well known and used extensively that the lowest eigenmodes of the QCD quark Dirac operator are described by random matrix theory. More recently it was shown that the high-temerature cross-over to the quark-gluon plasma state is accompanied by an Anderson-type transition in the quark Dirac spectrum. In the talk I will review some recent results concerning this transition. (The presentation will be quite elementary, in particular no familiarity with QCD will be assumed.)

Current approaches require a much closer link between physicists, chemists, computational scientists, on the one hand, and biologists/medical scientists, on the other, as well as the acquisition of a shared “language” and background. The aim of the school is to introduce young African researchers to the latest developments in the field of molecular biophysics, and to help forge links between theoretical and experimental communities, acting as a focus for the emerging biophysical sciences in Africa. The rapid development in the fields of biophysics, structural biology and nanotechnology has made available a new range of tools and approaches that have revolutionized biological and medical research, by allowing scientists to understand biology at the molecular level, manipulate nano-particles and macromolecular objects, and to monitor the behavior of single molecules. These developments are strongly connected to advances in computational biology and structural bioinformatics - ranging from structural biology to nanobiophysics, nanomedicine, single-molecule approaches - and with a revolutionary impact on biotechnology, pharmacology, drug delivery and early diagnostics of wide spread diseases.

Europe/Rome Actively spinning particles attracted much attention in recent years, mostly from a point of view of their ability to self-assemble on the liquid surface. On the other hand, the control of surface flows using surface waves has led to interesting analogies with optical traps for microparticles and ultracold atoms. In this talk I will present recent experiments on the confinement of active spinners within a wave-driven vortex lattice, also referred to as liquid metamaterial. I will discuss properties of the surface flow generated by two orthogonal standing waves. The spinners can be efficiently manipulated in such a flow to either occupy stationary orbits within a metamaterial cell, or they can be moved between the cells. I will discuss forces acting on the spinners in such flows and will show how multiple spinners interact to form stable self-organised configurations. ICTP ICTP pio@ictp.it

Europe/Rome Surface adherent microbial consortia, biofilm growth, is a predominant growth mode for bacteria and other microorganisms in nature. While there is considerable literature related to the negative aspects of the biofilms including chronic infections and industrial biofouling, they can also be harnessed as biotechnological tools such as in waste water treatment and remediation of environmental pollutions. We are interested in identifying fluid conditions favouring or discouraging bacteria attachment and formation of biofilms and evaluating the role of the surface waves and vibration in the biofilm formation. Our results show that the formation of the biofilms is strongly affected by the surface wave. Deterministic flows in a thin layer of nutrient medium promote the growth of patterned biofilms while chaotic and turbulent fluid motion reduces it. The settlement of bacteria and the locations of biofilms differ from the sedimentation patterns
