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.

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.

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.

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.

Building Bridges: Towards a Unified Picture of Stellar and Black Hole Binary Accretion and Evolution
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.

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.
