Holomorphic differentials on Riemann surfaces have long held a distinguished place in low dimensional geometry, dynamics, and representation theory. Recently it has become apparent that they constitute a common feature of several other highly active areas of current research in mathematics and also at the interface with physics.

The fields of spintronics, quantum magnetism, topological matter, and quantum criticality have seen progress with breakthroughs in concepts, techniques, and materials. The unifying goals of these fields are to understand novel collective effects that arise in quantum condensed matter systems with common underlying physics, often united through topology and common symmetries. Despite these common goals, these areas of research are still largely unconnected. This program will offer an opportunity for synergies and defining of new directions.

Representation theory is the study of the basic symmetries of mathematics and physics. Recently, it has known some spectacular developments, thanks to the introduction of new technics such as categorical representations or parity sheaves. The continued development of the subject has motivated a trimester in representation theory at the IHP that will take place in 2020 from January to March. This program will begin with an introductory conference. It will consist of 6 mini-courses on the main topics (categorifications and quantum groups, quiver varieties, character varieties, geometric representation theory). It is devoted to younger researchers, but also to senior ones in order to promote the discussions between young mathematicians and seniors.

A complete understanding of quantum gravity, as it pertains to our universe, remains one of the biggest challenges in theoretical physics. As our observational constraints on the early universe and black hole physics improve, this theoretical challenge has become even more urgent. This conference aims to explore the latest developments in quantum gravity and string theory, ranging from ideas motivated from holographic dualities to new results developing the landscape of string theory vacua.

structure of the landscape of string theory solutions; emergence of spacetime from other degrees of freedom; quantum information aspects of quantum gravity; recent developments in AdS/CFT; QFT methods applied to gravitational problems, such as the analytic conformal bootstrap and UV deformations of QFT; perturbative amplitudes in gravity and string theory

This is the 9th in series of international conference focussing on aspects of quantum walks and quantum simulation. Quantum simulation has recently established itself as an area of study in quantum physics that merges fundamental and applied questions. Such an interaction results in a more operational understanding of aspects of quantum mechanics in terms of nature description. The idea to simulate the dynamics of a quantum system by a quantum device was first introduced by Richard Feynman and developed in different frameworks, from mathematics to Computer Science and fundamental physics.

Coming to Melbourne, Australia 28-31 January 2020, the 10th International Conference on Spontaneous Coherence in Excitonic Systems (ICSCE10) aims to bring together the community of researchers studying quantum collective phenomena in various kinds of electronic excitations in solids, and related phenomena in other physical systems.

1. Interlayer and indirect excitons, 2. Novel materials (organics, perovskites, 2D monolayers), 3. Exciton-polaritons, 4. Quantum dots, 5. Ultrastrong coupling, 6. Spontaneous coherence in cold atomic, plasmonic, and other systems.

This conference will bring together experts in cosmology, particle physics, and fundamental theory to address how and when the universe thermalizes following inflation, and the associated particle physics and dark matter phenomenology. Important topics that will be covered include hidden sector model building in the LHC era, thermalization of the universe following inflation, possibilities of post-inflation cosmic history prior to nucleosynthesis, and associated experimental signatures. The conference aims to attract researchers in different areas to develop new directions in model building and establish new experimental paths for probing early universe cosmology and dark matter phenomenology.

The focus of this workshop will be on different aspects of modern theoretical cosmology, the challenges of the theory being consistent with experimental data, and the unavoidable connection of cosmological models with the quantum nature of the vacuum. A basic question in modern cosmology is: why we do not see vacuum fluctuations at cosmological scale? In addition, should the singularities of cosmological theories be treated as necessary ingredients of the classical theory or should them be considered as indicators of an underlying quantum theory, yet to be discovered? We aim to bring along to this workshop all the leading scientists working on those problems and discuss state of the art results on the above, strongly interdependent, areas of fundamental physics. The workshop will hence cover topics related to modified theories of gravity, theories of dark energy and inflation, the description of the universe’s evolution according to these theories and the incipient but compulsory modification of those within the theoretical frameworks of quantum gravity, including loop quantum cosmology, an elegant theory providing up to date a singularity free cosmological evolution. Describing and understanding the quantum vacuum is always a challenge to all these theories, as is also the comprehension of the main manifestation available of the quantum vacuum at nanometric scales, namely the Casimir effect (e.g., when confronted with van der Waals forces).

Significant developments in the spectral analysis of non-self-adjoint operators since the turn of the millennium include the explicit construction of well-localised almost-eigenvectors, the systematisation of the notion of pseudospectra and the rigorous setting of unbounded solvers for evolution problems. At the same time, a deep understanding of complicated physical phenomena such as cloaking in metamaterials, turbulence and explosive behaviour, has been achieved by means of close examination of the underlying non-self-adjoint operators. These developments involve combining techniques from diverse disciplines and in recent years groups who had been working on similar problems from different perspectives, often using different terminology, have been unaware of each other.

Active matter is a class of non-equilibrium, many-body systems that consist of individual energy-transducing components. The collective dynamics of such active entities underlies phenomena on scales from the molecular to the macroscopic, and it includes both living and non-living systems. The field of active matter focuses on understanding how the collective behaviors of internally driven components can give rise to patterns of motion and stress on large scales. While active matter systems violate detailed balance at the molecular scale, it remains unclear how such non-equilibrium dynamics manifests itself and can be quantified at meso- and macroscopic scales. In particular, it is interesting to investigate, given a particular set of microscopic elementary units, what range of possible macroscopic patterns, structures, dynamics and functionalities can be realized. The conference will bring together experimental and theoretical researchers from a broad range of disciplines to discuss recent advances that have transformed active matter into a rapidly growing field that spans diverse disciplines, ranging from physics to biology, to materials science and engineering.

Continuing rapid development in the field of chromatin biology has lately attracted enormous interest among biologists, physicists and mathematicians. Recently, the static structure of the folded genome inside the cell nucleus has been determined with increasingly high resolution. Special features of genome folding, such as loops, A/B compartments and chromosome territories, were identified and have inspired models rooted in polymer physics. Studies of the roles of these features in gene regulation and other biological processes are currently ongoing. In addition, research on chromatin dynamics has shown that the genome moves in space and time, thus these structural features might be dynamic, too. Currently, it is not clear how to reconcile the static picture with the dynamic nature of the genome. Following the recent surge in activity on both the biology and physics fronts, this conference aims to provide a platform that would facilitate an interdisciplinary exchange, cultivate new ideas and identify new frontiers.

The application of topology to physics has become an integral part of a second quantum revolution in the sciences. The discovery of topological insulators and progress towards topological superconductors realizing non-abelian statistics has moved topological phases of matter onto the center stage in the interaction of topology and physics beyond the quantum Hall effect. While topological physics has been intensively investigated by physicists for the last few decades, the mathematical theory lags far behind. One challenge is formulating the right definition of topological phases of matter, which is closely related to the notoriously difficult problem of finding a rigorous mathematical formulation of quantum field theory. In this summer school, we will focus on two relatively mature foundational topics, and two new directions in the mathematics of topological phases of matter.

This conference will highlight the diverse applications of emerging spatio-temporal quantum control techniques as well as the novel theoretical and experimental tools being developed to advance these techniques. The implications of many-body quantum control are far-reaching: stabilizing entangled states, realizing new forms of topological order, enhanced precision measurements, guided quantum dynamics for computation, probing quantum chaos, etc. The goal of this conference will be to survey both recent experimental developments in both spatial and temporal control for analysis of many-body quantum optical systems, and recent theoretical progress, with the purpose of identifying fruitful future areas for exploration.

This conference contains contributions that give an overview of the current research in geometric mechanics. This scientific subject is simultaneously close to mathematics, physics, and engineering and its general philosophy consists in taking advantage of fruitful interactions between geometry on the one hand and dynamics and mechanics on the other. This conference will be the occasion to celebrate the 70th birthday of Tudor Ratiu who over the years has made many fundamental contributions in the development of this field.

Theoretical aspects of applied mathematical research on nonlinear waves and coherent structures are relevant to subjects as diverse as general relativity, high-energy particle and plasma physics, fluid and solid mechanics, nonlinear electrical circuits, Bose-Einstein condensation, nonlinear optics, random media, atmosphere and ocean dynamics, chemical reactions, and biology. Remarkable agreement between theory and experiments can be claimed in many of these fields. The goals of the conference are to provide a forum for the development of mathematical methods and tools, to foster cross-fertilization among different fields of application, and most crucially to enable communication between the mathematicians who build the theory and the scientists who use it. The conference program will consist of presentations on subjects ranging from basic mathematical research to concrete applications.

This conference is the next edition in a long line of conferences starting in 1986 at the University of Canterbury, UK. This series of international conferences aims at bringing together leading scientists and young researchers in the field of Clifford algebras and their various applications in mathematics, physics, engineering and other applied sciences. The English mathematician and philosopher William Kingdon Clifford (1845-1879) is best remembered for his geometric algebras, nowadays better known in mathematics as Clifford algebras, named so in his honour, but he also contributed significantly to other branches of mathematics, especially geometry.

Topological properties of gauge theories find application in the characterization of novel phases of matter and in establishing nonperturbative phenomena such as the duality relations between quantum field theories in three and four spacetime dimensions. This conference is meant to expose the current status of research in several domains dealing with topology and duality

Equilibrium statistical physics provides an extremely powerful, universal formalism that tells us how many-particle systems in thermal equilibrium behave, and how we can characterize their properties by only a few macroscopic quantities. However, most systems and processes found in nature are out of equilibrium. Think of any living organism, or directed transport in cells mediated by molecular motors. Often these systems consist of only a few entities and are so small that thermal fluctuations play a prominent role. It has been a vision from the early days of statistical mechanics to develop a theoretical description for such small non-equilibrium systems that is comparably powerful and universal as is equilibrium statistical physics. The aim of this program is to bring together the leading experts in (non-equilibrium) statistical physics to critically discuss and evaluate the latest developments towards a universal theory for non-equilibrium systems.

Modularity is at the heart of many deep results in mathematics--from the proof of Fermat’s last theorem to moonshine to the Langlands correspondence. At the same time, modular group representations and automorphic forms underlie many interesting physical phenomena in quantum field theory and string theory, including understanding of dualities, boundary conditions, and supersymmetric black holes, among other things. This conference will bring together physicists and mathematicians to discuss emerging connections between a web of fundamental objects in physics and mathematics, united in the crucial role played by modularity.

A fascinating and surprising phenomenon that can occur in fluid and plasma turbulence is the spontaneous formation of arrays of layers in which material properties such as density adopt a so-called “staircase” structure. The most striking examples are potential vorticity staircases in planetary atmospheres, and thermohaline staircases in the oceans. Theoretical considerations suggest that layering also plays an important role in stellar interiors (particularly through various double-diffusive processes) and in fusion confinement devices (the so-called E x B staircase). Understanding the phenomenon of layering is, therefore, not only of intrinsic scientific interest (e.g., is there a common thread to layering in these very different contexts?), but is also crucial for an accurate description of turbulent transport in, for example, models of large-scale ocean flow, the evolution of stellar interiors and confinement in tokamaks.

This is a two-week program gathering mathematicians and physicists interested in the statistical physics of strongly correlated and long range random particle systems. These particle systems include Gibbs point processes such as Coulomb gases, determinantal point process, eigenvalues of random matrices, etc. They are linked to mathematical long-standing challenges such as the crystallization and best packing conjectures among others. One aspect that we want to put forward in this meeting is that the pioneering tools from classical statistical mechanics à la Ruelle, Lanford, Lebowitz may not have been used enough for the study of these particle systems yet.
