Quantization in Derived Algebraic Geometry and Representation Theory
02 mai 2021 - 07 mai 2021 • Oaxaca, Mexique
Organisateur:
Casa Matemática Oaxaca (CMO) in Mexico, and the Banff International Research Station for Mathematical Innovation and Discovery (BIRS) in Banff, Canada
Résumé:
An essential paradigm in science is solving a problem through the study of its symmetries. Whether dealing with a chemical, physical, or mathematical system, its symmetries are intimately related to the conservation laws characterizing the system itself. Therefore, their study leads us to its full understanding. Quantum groups are deformations of the most elementary symmetries in Nature, describing, for example, infinitesimal layers of ice. They first appeared in the eighties as symmetries of one and two-dimensional statistical mechanical models and are nowadays ubiquitous objects in mathematics. Quantum groups represent only an instance of the more general Theory of Quantization, in which the procedure of "deforming" classical structures gives rise to their "quantum" analog. This theory proved soon to have spectacular connections with many and only apparently unrelated areas of mathematics and physics, especially in representation theory (as described above), algebraic geometry (in particular the theory of moduli spaces), and theoretical physics (e.g. gauge theory). The present workshop aims to provide a survey of the state of the art of the Quantization Theory, with a special emphasis on using advanced techniques from (derived) algebraic geometry to the realm of Quantization.

Analysis on Singular Spaces
16 mai 2021 - 21 mai 2021 • Oaxaca, Mexique
Organisateur:
Casa Matemática Oaxaca (CMO) in Mexico, and the Banff International Research Station for Mathematical Innovation and Discovery (BIRS) in Banff, Canada
Résumé:
The presence of singularity in mathematics and physics is an omnipresent phenomena which is the subject of an enormous amount of current research. One reason for this is that techniques which are useful and well understood in the context of smooth spaces do not carry over automatically to singular spaces in general. Depending on the type of singularity involved, one might find that a theorem which is true in the smooth setting requires modification even to make sense in a particular singular setting, and a singular object with extra structure may lead to a generalization of a theorem in which that extra structure plays a role.

Quantum chaos and number theory
23 mai 2021 - 27 mai 2021 • The Steinhardt Museum of Natural History, Tel Aviv University, Israël
Résumé:
The conference “Analytic Number Theory, Quantum Chaos and their Interfaces” aims at gathering distinguished researchers working in either of the disciplines to discuss recent research advances in these fields, and serve as a playground for the exchange of ideas between these, rather diverse, research communities. Another purpose of our conference is to provide a solid educational platform for more junior researchers (PhD students, postdoctoral researchers and early career permanent faculty) who aspire to conduct research in the relevant fields and expose them to some of the outstanding results and open problems as well as to meet other researchers with similar academic interests, with high potential to start new research collaborations. Being a home to Professor Zeev Rudnick, who has contributed greatly to unifying the main subjects of the conference and established some relevant fundamental results in these fields, Tel Aviv University is a natural place for such a meeting to take place.

Recent Advances in the Physics of Elastic Films
24 mai 2021 - 27 mai 2021 • UC Santa Barbara, États-Unis
Organisateur:
Kavli Institute for Theoretical Physics (KITP)
Résumé:
Thin elastic films can be found everywhere: they occur naturally (lipid membranes, viral capsids, plant leaves, epithelial tissues, seashells, etc.) and as man-made materials (paper, graphene, fabrics, concrete shells, etc.). Since their resistance to bending must obey purely geometric surface constraints, stress and geometry are intricately coupled, often leading to unexpected and very nonlinear responses to perturbations. Recent progress in theoretical and experimental approaches, as well as novel technological applications, have advanced the frontier of this field, but also brought challenging new problems into focus, to which this conference is dedicated. Examples of interest include extreme mechanics, the cross-talk between stress and geometry, fluctuations in and out of equilibrium, frustrated internal stresses, and wetting of deformable sheets. We strive for a highly multidisciplinary meeting, in which experimentalists, theorists, and numerical simulators explore open questions in both biological and man-made model systems, examine the promise of novel theoretical and numerical techniques, identify the current frontier of understanding, and speculate on what type of new ideas or tools might be needed to push it further.

Entangled Quantum States of Matter: Classification, Creation, Manipulation, Detection
21 jui 2021 - 24 jui 2021 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
This conference will explore many aspects of entangled quantum states of matter, with an eye towards their eventual experimental realization. These include non-Fermi liquids, symmetry-protected topological states, and topologically-ordered quantum matter such as gapped and gapless quantum spin liquids. Some of these states harbor nontrivial boundary or edge modes which will also be highlighted. Different topics will be covered including: the classification of entangled topological states which provide a roadmap of what is possible; investigations on how to engineer models built with realistic ingredients guided by theoretical explorations of their phase diagrams; and proposals for the right observables to detect and manipulate these states which can bring them closer from an abstract idea to reality. This conference will bring together experts on many aspects of highly-entangled quantum matter and help connect experts on mathematical aspects of classification and those with numerical expertise that provide information on phase diagrams with experimentalists striving to engineer these states in the lab.

Thermodynamic Formalism for Geodesic Flows
27 jui 2021 - 02 jul 2021 • Oaxaca, Mexique
Organisateur:
Casa Matemática Oaxaca (CMO) in Mexico, and the Banff International Research Station for Mathematical Innovation and Discovery (BIRS) in Banff, Canada
Résumé:
This workshop will study this question for systems of geometric origin. One example of this is a particle bouncing inside a region -- think of a ball bouncing around a billiard table, or a light beam bouncing around a room whose walls are mirrors. If the walls are flat then the behavior is fairly predictable, but if they are curved then one often observes random-looking behavior in the long run. Or imagine walking in a straight line along a surface; if the surface is flat then changing the starting point a little will lead to a predictable change in the trajectory. However, if the surface is curved like a saddle then different trajectories will spread out and your location after walking for a long time will eventually seem to be random. The task of giving precise descriptions of systems such as these requires a more complete development of the theory of thermodynamic formalism for systems of geometric origin, which is precisely the goal of this workshop.

Transport and Efficient Energy Conversion in Quantum Systems
30 aou 2021 - 02 sep 2021 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
Several communities of experimental and theoretical physics are devoted to studying the problem of transport and energy conversion in quantum systems away from equilibrium. In statistical physics, these topics have been traditionally addressed mainly in the classical realm. In condensed matter and atomic physics, the traditional context has been quantum charge and spin transport. Recent progress includes the application of ideas from quantum information to understand the emergence of thermodynamical concepts and the creation in experiments of quantum coherent systems of various scales with a novel degree of control. These developments motivate work on fundamental challenges like the creation of optimal protocols for energy/information transport as well as state preparation. The aim of this conference is to provide a survey of the most recent advances in the area, bringing together experts across all these fields.

IAMP – EMS Summer School in Mathematical Physics 2021 — Summer School on ''Quantum information in many-body physics: a mathematical invitation''
13 sep 2021 - 17 sep 2021 • Munich, Allemagne
Résumé:
When many quantum particles interact, they can organize themselves into highly entangled states with unexpected properties that transcend those of the individual constituents. The description of those states and their properties is typically rather challenging - not only from a mathematical point of view. In the last 15 years, concepts and tools from quantum information theory (QIT) have proven highly useful in investigating such systems. This new perspective aims to characterize and classify the complexity in large quantum systems.

Mathematical Foundations of the Swampland Program
13 sep 2021 - 24 sep 2021 • Mainz, Allemagne
Organisateur:
Mainz Institute for Theoretical Physics, Johannes Gutenberg University
Résumé:
Recently, there has been great interest in determining criteria which differentiate between effective low-energy field theories which can be consistently completed in the ultraviolet into quantum gravity, said to be in the ‘Landscape’, from theories which appear consistent but nonetheless defy such a coupling to quantum gravity, the so-called ‘Swampland’. A number of such criteria, or Swampland Conjectures, have been proposed in the literature and attracted considerable interest in the high energy physics community. If confirmed, they have far-reaching consequences for physics and cosmology, such as for the structure of large field inflation in early time cosmology or for the mechanism responsible for the observed late-time acceleration of the universe, to name but the most striking ones. On the other hand, the Swampland Conjectures translate, in the context of string theory, into conjectures regarding the structure of possible compactifications, or string geometries. String theory is therefore in a unique position to quantitatively test - and possibly refine - such general Swampland Conjectures. This Scientific Program proposes to study these intriguing connections between general properties of quantum gravity and the geometry of string compactifications. It aims to bring together world experts working at the forefront of research in string theory, field theoretic aspects of quantum gravity, and geometry at this unique time in which our understanding of the Swampland is quickly evolving.

Subfactors, Vertex Operator Algebras, and Tensor Categories
19 sep 2021 - 24 sep 2021 • Hangzhou, Chine
Organisateur:
Institute for Advanced Study in Mathematics (IASM) in Hangzhou, China, and the Banff International Research Station for Mathematical Innovation and Discovery (BIRS) in Banff, Canada
Résumé:
Subfactors and vertex operator algebras are mathematical structures that at first glance appear very different, but both are used in the mathematical study of quantum field theory. In particular, vertex operator algebras are algebraic structures arising in two-dimensional conformal field theory (CFT), a quantum field theory with applications ranging from string theory to condensed matter physics to quantum computing. On the other hand, subfactors are closely related to conformal nets, which are a functional-analytic approach to CFT. Because they are both mathematical descriptions the same quantum field theory, the theories of vertex operator algebras and conformal nets are widely believed to be equivalent, but only in the last few years has there been substantial progress in establishing an equivalence. As many important results in conformal field theory have been established for either vertex operator algebras or conformal nets, but not necessarily both, developing connections and equivalences will be useful for answering open questions in both mathematical formulations of CFT.

Non-Equilibrium Universality in Many-Body Physics
27 sep 2021 - 30 sep 2021 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
The advent of quantum simulators have ushered a new era of non-equilibrium many-body physics and has sparked a dialogue between seemingly disparate fields. This conference will explore universal aspects of many-body systems far from equilibrium at the interface of statistical physics, AMO, condensed matter and high-energy physics, by bringing together scientists from these diverse communities. Our focus is on novel phases of matter far from equilibrium and their associated universality classes that emerge beyond equilibrium paradigms. Diverse topics will be covered including short-time universality, entanglement dynamics, and mapping between classical and quantum non-equilibrium systems. Our goal is to identify aspects of high-energy physics that can inform non-equilibrium condensed and AMO systems and vice versa, with an eye towards realizing experiments which can sharpen our understanding of far-from-equilibrium universality.

Quantum Field Theory at the Boundary
27 sep 2021 - 08 oct 2021 • Mainz, Allemagne
Organisateur:
Mainz Institute for Theoretical Physics, Johannes Gutenberg University
Résumé:
Boundaries and defects have been at the heart of crucial developments in theoretical physics in the last 20 years: holography (field theories could live at the boundary of a higher- dimensional gravitational theory), entanglement (the entangling surface can be treated as a defect), black holes (the horizon is a boundary), topological insulators and semi-metals (the topologically-protected massless modes live at the boundary), and non-local operators such as Wilson and ‘t Hooft lines (defects defined by appropriate boundary conditions). Additionally, many other areas have made major advances in recent years whose implications for quantum field theory with boundaries and defects have yet to be explored fully: the conformal bootstrap, dualities among (2+1)d quantum field theories, supersymmetric localization, integrability, and so on. However, progress in these areas has largely been carried out by separated communities working in isolation from the others. This scientific program thus aims to bring together a diverse group of leading theorists interested in boundaries and defects in quantum field theory, from the formal/mathematical to the applied, to forge collaborations between different areas, identify common subjects and complementary approaches, and set the agenda for future developments and new applications.
Sujets:
The three broad focus areas will be: Conformal field theories with boundaries and defects Supersymmetry and Duality with boundaries and defects Curved space, gravity and entanglement

GBDSWT — Generic Behavior of Dispersive Solutions and Wave Turbulence
18 oct 2021 - 22 oct 2021 • Providence, États-Unis
Organisateur:
ICERM
Résumé:
The large-time behavior of (generic) solutions of nonlinear dispersive equations set on bounded domains is almost completely open as far as rigorous analysis goes, and fairly mysterious, even from a less rigorous viewpoint. Under the assumption of weak nonlinearity, physicists and applied mathematicians have devised a theory to approach this question, known as weak turbulence, a branch of statistical physics. Weak turbulence theory predicts that the equation will enter a chaotic regime, where the exchange of energy in phase space is governed by the so-called kinetic wave equation. Justifying the derivation of the kinetic wave equation is a fascinating mathematical task, for which some results are already known, but whose solution will likely require input from nonlinear PDEs, but also probability theory. Intimately related questions are the question of Sobolev growth (how much can or does, the Sobolev norm of a nonlinear dispersive equation grow over time), as well as the analysis of nonlinear dispersive equations with random data. These questions have already generated a lot of interest, but much remains to be discovered: our understanding is extremely lacunar.

Flux tubes, Quark Confinement and Exotic Hadrons
18 jan 2022 - 21 jan 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
Understanding how color is confined in QCD, and the binding of quarks into hadrons, is one of the major unresolved challenges in fundamental physics. The central piece in this puzzle is the chromoelectric flux tube, or confining string, which holds quarks together. In recent years, tantalizing new insights into the dynamical properties of confining strings have been obtained using various theoretical tools such as effective string theory, integrability, the modern S-matrix bootstrap, and gauge/gravity duality. Lattice gauge theory supplies important information about the spectrum of flux tube excitations. Finally, the recent experimental discovery of heavy flavor tetraquarks provides a direct observational probe of flux tube junctions. This conference will bring together experts in these different fields to initiate the exchange of ideas and stimulate future cross-disciplinary developments.

14 mar 2022 - 17 mar 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
Binary systems are ubiquitous in nature, from stars to the supermassive black holes expected to reside in galactic nuclei. In many circumstances, the binary system is enveloped by circumbinary gas. How does circumbinary gas evolve and influence the embedded binary? What observational signatures of this gas are most informative? What novel numerical techniques must we deploy to better model these systems? This conference will bring together two distinct communities: those working on massive black hole binaries with those working on stellar binaries. Because recent years have seen remarkable progress in observations of stellar binaries, and numerical modeling of both stars and black holes, now is the ideal time to bring together these two groups. The conference will highlight the remarkable similarities of problems at such varied astrophysical scales, and shed light on the crucial next steps for pushing the boundaries of our knowledge.

Interdisciplinary Developments in Neutrino Physics
28 mar 2022 - 31 mar 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
The goal of this conference is to survey the interdisciplinary avenues in modern neutrino physics, with a threefold overarching set of aims: (1) to maximize the new physics potential of present and upcoming experimental data, (2) to understand new directions in the quest for high-precision neutrino cross sections, including synergy with lattice QCD; and, (3) to ensure that the impact of neutrinos on astrophysical and cosmological processes is comprehensively addressed. Particular attention will be given to exploring connections between neutrinos and gravitational waves, cosmological data, sources for IceCube’s astrophysical neutrino events, implications of the latest sterile searches for cosmology and astrophysics, and an assessment of the role of the neutrino detectors as astrophysical observatories.

Storming the Gravitational Wave Frontier
19 avr 2022 - 22 avr 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
The detection of gravitational waves by Advanced LIGO/Virgo has opened a new frontier in physics, with impact on areas ranging from field theory through stellar evolution and cosmology. It has also seeded new connections between theoretical communities, especially between field theorists and classical relativists. An even brighter future lies ahead, with more sensitive ground-based detectors and, eventually, a space-based observatory. Current and future experiments demand precision modelling of gravitational-wave signals in order to interpret the strongest gravitational-wave events and to enable sensitive searches for new physics which may be embedded in these signals. The conference will bring together experts from three communities: classical relativity, effective field theory, and scattering amplitudes. Building on the current state of the art, we will discuss the needs of the next generation of gravitational-wave experiments; identify which challenges theory must overcome; highlight recent advances in gravitational wave modelling for more detailed study; and uncover the most promising emerging tools and techniques from classical and quantum field theory for further development.

Opportunities and Challenges in Few-Body Physics: Unitarity and Beyond
23 mai 2022 - 26 mai 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
This conference will bring together a diverse set of scientists interested in the broad topic of few-body physics, providing a snapshot of the current status of few-body physics near unitarity, where the two-body scattering length is the largest length scale in the problem. Successes and open challenges in the area of atomic and nuclear physics, which are--despite the vastly different length and energy scales--intimately linked through, e.g., the three-body Efimov effect, will be highlighted. A major objective is to provide a platform for cross-fertilization between theory and experiment as well as between different research areas (such as nuclear, atomic, molecular, condensed matter, high-energy, and mathematical physics), with universality and its implied organizing principles as a unifying connection.

Quantum and Thermal Electrodynamic Fluctuations in the Presence of Matter: Progress and Challenges
11 jul 2022 - 14 jul 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
This conference will explore many aspects of classical and quantum fluctuating electromagnetic fields in the presence of matter, which impact a wide range of fundamental and practical phenomena in domains of physics, chemistry end engineering. Building upon the significant milestones achieved in the realms of the Casimir interactions between bodies, and the role of quantum field fluctuations in heat transfer in the near- and far-fields, we plan to address a plethora of novel questions and remaining puzzles: the ramifications of 2D (topological) and non-reciprocal materials, the possibility of detecting quantum friction, the discord between different experimental and theoretical results. Unraveling these puzzles will have profound impacts from fundamental science to novel applications of materials. The conference will bring together theorists and experimentalists who will address unsettled topics and possible new experimental directions that could elucidate them.
