Europe/Rome 2019-02-28 11:00:00 2019-02-28 12:00:00 ICTP Seminar Series in Condensed Matter and Statistical Physics: Combining Machine Learning and Logic for Complex Systems 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 2019-03-12 11:00:00 2019-03-12 12:00:00 Joint ICTP/SISSA Statistical Physics Seminar: Granular Brownian Motion Granular materials are made of macroscopic particles, called grains: sand, rice, sugar and powders are typical examples. They are important in our everyday life, in many industrial applications and in the prevention of geophysical hazards. In physics, mainly in the realm of non-equilibrium statistical mechanics, granular systems are an inspiring source of phenomena and questions. The simplest model of granular material is a "fluid" made of inelastic hard spheres. For such a system - in the dilute limit - the classical program of kinetic theory Boltzmann equation, Chapman-Enskog-based hydrodynamics, and much more) has been developed by physicists and mathematicians in the last decades. In this seminar, after recalling a few key results of such a theoretical activity, I will focus on a series of experiments made in my laboratory in the last 5 years. They concern the statistical properties of a massive probe immersed in a steady state granular fluid. The fluid is obtained by vibro-fluidization of a large number of solid spheres of different materials, while the probe is a rigid rotator whose angular displacement and angular velocity are the key observables. In the dilute limit one conjectures a Markovian approximation for the rotator's dynamics which explains many aspects of the experiment, including a qualitative understanding of "motor effects" in the presence of rotator's geometrical asymmetries. Further noticeable facts appear when the granular fluid is no more dilute, mainly anomalous diffusion and non-monotonous viscosity. References: A. Gnoli, L. de Arcangelis, F. Giacco, E. Lippiello, M.

Europe/Rome 2019-02-18 07:00:00 2019-02-22 21:00:00 Advanced School on Ubiquitous Quantum Physics: the New Quantum Revolution | (smr 3273) 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.

The Workshop follows a School of the same title focussing from a more specialized perspective upon the same three topics: 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. Aim of the Workshop is to bring together experts that will present their latest developments thus providing all participants, among them students who attended the School, with a unique venue for sharing and discussing novel trends and ideas, integrating the fundamentals with the ongoing state of the various disciplines.

ICTP does not operate through external agencies nor contacts invitees via phone calls for accommodation purposes, and ICTP does not request credit card data. * * *   Online application is open until 10 February 2019 - - -   This conference will address recent theoretical and experimental developments in quantum measurement, underscoring common themes from the perspectives of foundations of quantum mechanics, quantum information processing, quantum optics, condensed matter physics and metrology. Rooted in the early history of quantum mechanics, the field of Quantum Measurement has evolved from a purely mathematical formulation to an active research topic, embedded in a broad spectrum of subfields, ranging from quantum optics to condensed matter physics. It involves a variety of techniques, including quantum limited, fast, non-invasive measurements. As a versatile tool in an advanced quantum toolbox, quantum measurements could be empowered for the design of novel protocols, including active and passive error correction codes, quantum feedback control, precision measurements, quantum state discrimination, quantum metrology, quantum simulations and more. In this context of diversified research, this meeting will bring together expert theorists and experimentalists, employing different facets of quantum measurement, with the goal of identifying common themes, and cross-fertilizing with new ideas. A Poster Session will also be organized, and interested candidates are invited to upload a short abstract of their proposed posters during the online application process (max. half page, in pdf format). Poster presentation is not mandatory, however participants are encouraged to present their results.   Topics      Foundations of quantum mechanics     Quantum measurement in information processing     Quantum measurements in nanodevices     Quantum measurement and thermodynamics     Quantum metrology and precision measurements   Speakers  A.
