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.

Organizer:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Abstract:
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.

Particle & AMO Physicists Discussing Quantum Sensors and New Physics
06 Dec 2021 - 17 Dec 2021 • Garching, Germany
Organizer:
MIAPP - Munich Institute for Astro- and Particle Physics
Abstract:
In the last decade or so quantum technologies have made tremendous progress, from redefining the second to establishing quantum supremacy. This unequalled ability to control quantum systems leads to a potential to make measurements with unprecedented accuracy. Quantum technologies have already been at play in various fronts such as the observation of gravitational waves and in searches for CP violation by bounding the electric dipole moments of the electron and the neutron. At the same time, the field of particle physics, given its primary objective to decipher the fundamental laws of nature, is in a critical junction.

Workshop I: Multiscale Approaches in Quantum Mechanics
28 Mar 2022 - 01 Apr 2022 • Los Angeles, CA, United States
Organizer:
IPAM - Institute for Pure & Applied Mathematics, an NSF Math Institute at UCLA
Abstract:
This workshop will set the stage and define research directions for the rest of the program. The idea is to achieve a healthy mix between researchers developing quantum theories and methods on different spatial and temporal scales, providing a forum to discuss the advances in multiscale modeling in quantum mechanics and pave the way to stronger coupling between existing methods and completely novel quantum approaches. The main question is how to integrate already existing quantum methods to reduce their weaknesses, improve their applicability, and enable quantum calculations on much larger scales? For example, electronic orbitals obtained from density-functional theory calculations are being increasingly used to compute correlation energies using many-body Green’s function theories and explicitly correlated methods. Such synergies provide a way to approach the exact solution of the Schroedinger equation, in addition to significantly accelerating the cost of explicit many-body calculations. On a much larger spatial scales, multiscale coupling of approximate many body Hamiltonians with Maxwell’s equations allows to unify microscopic and continuum treatments of van der Waals and Casimir interactions, eventually making it possible to push the boundaries of such calculations to macroscopic systems.

Workshop II: Model Reduction in Quantum Mechanics
11 Apr 2022 - 15 Apr 2022 • Los Angeles, CA, United States
Organizer:
IPAM - Institute for Pure & Applied Mathematics, an NSF Math Institute at UCLA
Abstract:
The first one is the rigorous mathematical derivation of reduced models from reference quantum models in some regimes such as the semiclassical limit, adiabatic limit, thermodynamic limit, and high/low density limit. New approaches have been developed in the past two decades, which lead to successful mathematical derivations of reduced models in a number of settings. However, in many settings the mathematical relations between reference and reduced models and the domain of validity of the latter still have to be clarified. The second aspect is concerned with effective interactions. Interactions between elementary particles typically have very simple functional form such as the Coulomb potential between two charged particles. However, upon solving the many-particle quantum mechanical equations, complex and intricate interactions emerge. The understanding and systematization of such interactions between composite objects provides a pathway to better understand quantum mechanics itself and constitutes the basis for developing coarse-grained approaches to describe interactions in large quantum systems. The third aspect is about simplified quasiparticle or collective mode descriptions of complicated quantum states, using one-particle spin-orbitals, plasmons, phonons, polarons, or excitons. Such objects are embedded in finite or infinite dimensional Hilbert spaces defined by the basis set utilized to expand the many-body wavefunction. Recently, many interesting efforts have been dedicated to analyzing and visualizing quantum states in Hilbert spaces, as well as to map and embed Hilbert spaces between different quantum systems. Such mapping and embedding of Hilbert spaces brings out novel insights into the intricate nature of quantum fluctuations and should ultimately allow to develop better and more reliable approximations for solving complex quantum systems.

Workshop III: Large-Scale Certified Numerical Methods in Quantum Mechanics
02 May 2022 - 06 May 2022 • Los Angeles, CA, United States
Organizer:
IPAM - Institute for Pure & Applied Mathematics, an NSF Math Institute at UCLA
Abstract:
Simulating very large quantum systems require new numerical methods and algorithms. Such simulations indeed lead to solving linear and nonlinear systems of equations and eigenvalue problems, that are characterized by high dimensionality, large ranks (for tensor problems), and extreme scale. They must exploit massive parallelism in both space and time and rank-reduction methods, through deterministic or stochastic approaches, optimized data structures, and minimize communication. It is also key to have tools at hands to assess the quality of the simulation results. Error analysis is of major relevance in the simulation of quantum systems, but to date, it has received less attention than in other fields such as fluid or structure dynamics. The error between the exact and computed values of a given physical quantity of interest (QOI), e.g. the dissociation energy of a molecule, has several origins: a model error (resulting from the choice of a computationally tractable, but not extremely accurate, model, e.g. Kohn-Sham with B3LYP functional), a discretization error (resulting from the choice of a finite basis set), an algorithmic error (due to the choice of stopping criteria in Self-Consistent Field and other iterative algorithms), an implementation error (due to possible bugs or uncontrolled round-off errors), a computing error (due to random hardware failures). Quantifying these different sources of errors is key for two reasons. First, guaranteed estimates on these five components of the error would allow one to supplement the computed value of the QOI returned by the numerical simulation with guaranteed error bars (certification of the result). Second, this would allow one to choose the parameters of the simulation (approximate model, discretization parameters, algorithm and stopping criteria, data structures?) in an optimal way in order to minimize the computational effort required to reach the target accuracy (error balancing). Since molecular simulation consumes a massive amount of CPU time in scientific research centers worldwide, this would have a major impact on the use of scientific computing resources.

QENS/WINS 2022
23 May 2022 - 27 May 2022 • San Sebastian, Spain
Abstract:
The next joint celebration QENS/WINS will constitute the 14th Edition of the QENS series and the 9th of the WINS workshops. The face-to-face Conference (QENS/WINS2022) will take place in San Sebastian, 23-27 May 2022. QENS focusses on the discussion and exchange of scientific ideas related to the investigation of atomic and molecular motions, while WINS deals with instrumental aspects of quasielastic and inelastic neutron scattering techniques. Though originally QENS and WINS were held in an independent way, the added value of their joint celebration has been put forward since it enhances their scope and impact on the scientific community related with the quasielastic and inelastic neutron scattering techniques. Young scientists involved in neutron scattering investigations can particularly profit from this joint event (and are especially welcome).

Workshop IV: Monte Carlo and Machine Learning Approaches in Quantum Mechanics
23 May 2022 - 27 May 2022 • Los Angeles, CA, United States
Organizer:
IPAM - Institute for Pure & Applied Mathematics, an NSF Math Institute at UCLA
Abstract:
Quantum mechanics has strong connections with probability theory and statistics. Quantum states are amenable to probabilistic interpretation based on laws of statistics. Many quantum problems can be reformulated in terms of Feynman’s path integral formulation, which amounts to computing quantum partition functions using statistical sampling techniques. In addition, new statistical learning approaches are emerging that aim to incorporate “quantumness” to ensure unitarity and long-range correlations that are so ubiquitous in quantum systems. Considering these recent developments, it appears timely to bring together the large community of people working on quantum systems and statistical techniques. This workshop will broadly address the reaches and limitations of statistics as applied to the modeling and understanding of quantum systems and highlight examples where quantum and statistical models enhance each other.

Quantum and Thermal Electrodynamic Fluctuations in the Presence of Matter: Progress and Challenges
11 Jul 2022 - 14 Jul 2022 • Santa Barbara, United States
Organizer:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Abstract:
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.
