Strings and Higher Dimensional Theories

HECAP Seminar: Gravity & Thermodynamics

Room: Leonardo Building - Euler Lecture Hall

Speaker(s): Shahin Sheikh Jabbari (IPM, Tehran)

Abstract. Last 50 years' developments have revealed deep relations between thermodynamics and gravity as formulated in Einstein general relativity, despite their apparent differences. These relations seem so fundamental and deep that they have prompted the idea that they may be telling us about the very nature of gravity. In this talk I review these salient features and discuss recent developments in the connection between gravity and thermodynamics. In particular, I describe how general covariance in gravity theories on spacetimes with a boundary leads to laws of thermodynamics at the boundary. We briefly discuss implications of these considerations for questions regarding black holes.

Europe/Rome Tridib Sadhu (TIFR Mumbai) Abstract: Although basic equilibrium concepts like state variables, thermodynamic potentials, etc do not straightforwardly extend for non-equilibrium states, an analogue of Landau free energy characterising macroscopic fluctuations could be defined based on a mathematical theory of large deviations. I shall present a few old and new exact results for such a quantity in a class of non-equilibrium transport models. These are interacting classical many-body systems with relations to quantum spin chains. Our new results show that similar to a thermodynamic potential, these free-energy-analogues are robust against variations of coupling with external baths, thereby strengthening the possibility of a thermodynamic description for non-equilibrium states. I shall explain how these exact results are derived using a tilted operator formalism and a matrix-product-representation for a specific integrable model [1]. Then, I shall recover these results using a minimal action solution of a hydrodynamic field theory [2], which applies to a wider class of systems, including those which are non-integrable. Refs.

CMSP Seminar (Joint ICTP/SISSA Statistical Physics): "Thermodynamic potential" for a class of non-equilibrium systems

Speaker(s): Tridib Sadhu (TIFR Mumbai)

Seminar Start Time: 11:00

Europe/Rome Carolina Vera is Full Professor at the School of Sciences of the University of Buenos Aires (UBA) and Principal Researcher of Argentina National Council of Sciences (CONICET). She has been the Director of the Argentinean-French Institute for Climate Studies and its impacts, jointly sponsored by UBA, CONICET, of Argentina and "Centre national de la recherche scientifique" (CNRS), Deputy Dean of the School of Sciences of UBA and Director of the Center for Atmosphere and Ocean Research (CIMA)/ UBA- CONICET. Between December 2019 and September 2021, she was Chief staff of the Minister of Science, Technology, and Innovation of Argentina. Dr. Vera has long research experience on understanding, simulating and predicting climate variability and change and its impact on socioeconomic sectors, like agriculture. She coordinated many recognized international research projects and programs related with climate variability and change. She has authored several peer-reviewed scientific journal articles and book chapters. She was awarded by the American Meteorological Society with the “Cleveland Abbe” Award, "For unselfish devotion to advancing and communicating climate science to decision makers and stakeholders in South America and across the world". She is currently Vice-Chair of WG1Bureau of the IPCC (Intergovernmental Panel for Climate Change). She was Coordinator of “Pampa Azul: the Interministerial initiative of Argentina for Ocean Sciences” and Coordinator of the report on the physical basis of climate change for the 3rd national communication of Climate Change of Argentina. She has served in International Panels like the Scientific Advisory Panel of the World Meteorological Organization, the Scientific Advisory Committee of the Inter-American Institute for Global Change (IAI), Future Earth Science Committee, World Climate Research Program (WCRP) Joint Scientific Committee, Independent Science Panel of the Research Program on Climate Change, Agriculture and Food Security (CCAFS), Scientific Committee of the Transformation to Sustainability Program of International Social Science Council (ISSC), and the Committee of the American Meteorological Society for Meteorology and Oceanography of the Southern Hemisphere. ABSTRACT: Variability in regional climate arises from natural and anthropogenic forcings, internal variability including the local expression of large-scale remote drivers, and the feedbacks between them. Due to the many possible drivers of variability and change, quantifying the interplay between internal variability and any externally forced component is crucial in attempts to attribute causes of regional climate changes and to increase the confidence on future regional climate change information. I will first briefly introduce the sources of regional variability that can be grouped in forcings controlling regional climate and the internal drivers of regional climate variability. I will discuss ways of managing uncertainties in regional climate change information and how to identify the physical causes of past and future regional climate change. I will then present a regional climate change attribution study of precipitation trend in a specific region and discuss the robustness and emergence of anthropogenic signal in future regional climate change. I will end by presenting the storylines methodology as a way of constructing regional climate information providing a set of physically coherent descriptions of plausible future changes at regional scales. The Colloquium will be held in the Budinich Lecture Hall on the ICTP Campus. All are welcome to attend. Light refreshments will be served after the event.

ICTP Colloquium on "Interplay between Natural Variability and Anthropogenic Climate Change at Regional Scales" by Prof. Carolina Vera, University of Buenos Aires - CONICET, Argentina

Address: Strada Costiera 11 34151 Trieste Italy

Room: Leonardo Building - Budinich Lecture Hall

Speaker(s): by Prof. Carolina Vera, University of Buenos Aires - CONICET, Argentina

Colloquium Start Time: 16:00

Europe/Rome Subir Sachdev is a condensed matter physicist well known for his research on quantum phase transitions and its application to a variety of quantum materials, such as the high temperature superconductors. His research seeks to illuminate the boundary between the everyday world we live in—in which many but not all phenomena can be explained through classical physics—and the subatomic world of quantum physics. These two worlds come together at a "quantum phase transition”, where there is a change in the macroscopic character of the quantum state describing a many-particle system, and manifestations of quantum entanglement appear naturally at long distances. His book Quantum Phase Transitions (Cambridge University Press, 1999 and 2011) has formed the basis of much subsequent research. More recently he pioneered the application of string theory to the study of quantum phase transitions in systems of ultracold bosons, and to the “strange metal” state found in many modern materials. Sachdev was educated in 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 as 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, and the Salam Distinguished Lecturer at the International Center for Theoretical Physics, Trieste in 2014. He is a former Member of ICTP's Scientific Council. Abstract of the Colloquium: Entanglement is the strangest feature of quantum theory, often dubbed ''spooky action at a distance’’. Quantum entanglement can occur on a macroscopic scale with trillions of electrons, leading to novel superconductors which can conduct electricity without resistance even at relatively high temperatures. These superconductors also display a “strange metal” regime in which individual electrons lose their identity. Related entanglement structures arise across the horizon of a black hole, and give rise to Hawking’s quantum paradox. I will introduce and describe these long-standing problems in two very different fields of physics, and review progress in resolving them using insights from the Sachdev-Ye-Kitaev model. All are welcome to attend. Light refreshments will be served on the Leonardo Building Terrace after the event. ICTP ICTP pio@ictp.it

Europe/Rome The ICTP Prize is awarded annually to young scientists from developing countries who have made outstanding and original contributions to physics. Rondrotiana Barimalala of the University of Cape Town, South Africa, and Narendra Ojha of the Physical Research Laboratory, Ahmedabad, India, were awarded the 2021 ICTP Prize for their important work on diverse aspects of climate change in Africa and Asia. Much of the work of Rondrotiana Barimalala has focussed on the role of the Indian Ocean on the climate of Madagascar and southern Africa. The ICTP Prize recognizes her pioneering contributions that have advanced the understanding of these interactions through her use of modelling tools and careful data analysis. A deeper understanding of the physical mechanisms driving climate in the region contributes to improved modelling of future climate conditions. This is crucial for Madagascar, a country that is on the brink of experiencing the world's first climate change famine, according to the United Nations World Food Programme. In India, where ICTP Prize winner Narendra Ojha is based, air pollution is a major health hazard for the country and indeed for all of South Asia. Air pollution also reduces agricultural productivity and therefore adversely impacts the economy of the region. Complex modelling is essential to unravel the roles of diverse emissions in air pollution over South Asia for designing mitigation strategies. The recipients of the 2021 ICTP Prize will be honoured at a ceremony at ICTP to be held on Wednesday 27 July 2022. More information and the programme for the Ceremony will be available in due course. Each year, the ICTP Prize is given in honour of a scientist who has made outstanding contributions to the field in which the prize is given. The 2021 ICTP Prize is dedicated to the memory of Jacob Bjerknes, who discovered the connection between sea surface temperature and easterly winds anomalies in the equatorial Pacific. He helped increase our understanding of the El Niño Southern Oscillation by suggesting that an anomalously warm spot in the eastern Pacific can weaken the east-west temperature difference, disrupting trade winds that push warm water to the west. The result is increasingly warm water toward the east.
