Materials Challenges for Memory
11 avr 2021 - 13 avr 2021 • Virtual Conference, États-Unis
Organisateur:
AIP – American Institute of Physics
Résumé:
The energy cost of storing and moving data is enormous, and is growing at such a rapid pace that within a few years the power demand may overwhelm some developed nations. Non-volatile memory (NVM) and neuromorphic computing are enabling critical advances in this area, but there are many scientific and technological challenges. This conference will cover the materials challenges of different memory technologies, from the fundamental processes and mechanisms, to industry perspectives on materials specifications and manufacturing.

IPAM-TNS-2021 — IPAM Workshop: Tensor Network States and Applications
19 avr 2021 - 23 avr 2021 • Los Angeles, États-Unis
Organisateur:
Institute for Pure & Applied Mathematics (IPAM), Los Angeles
Résumé:
Due to their high complexity, our understanding of strongly correlated quantum many-body systems is still limited. This concerns, for example, both static and dynamical equilibrium properties of fermionic systems and quantum magnets in condensed matter physics, as well as complex molecules with strong entanglement in quantum chemistry. Other big challenges are the analysis of non-equilibrium dynamics of closed systems, systems interacting with an environment, and transport problems. Tensor network states such as MPS, TTN, PEPS, and MERA are designed to capture the structure of entanglement in quantum systems in compressed representations. They are also particularly well-suited for the study of topological ordered phases of matter which cannot be described within the framework of spontaneous symmetry breaking. A better mathematical understanding of approximate tensor network representations is emerging for cycle-free networks like MPS and TTN. Current interesting questions concern, for example, the algorithmic stability and complexity, error accumulation, and the optimal choice of single-particle orbitals. Much less is known about the mathematical properties of formats like PEPS which allow cycles and are very natural physically for (D>1)-dimensional systems. The cycles can lead to mathematically intricate situations where, for example, the set of tensor network states is not closed. A major long-term challenge is to identify formats and algorithms that combine key physical properties of PEPS with the algorithmic robustness of MPS and TTN. In this workshop, we will focus on the interplay between specific applications and theoretical developments. In particular, we will discuss specific challenging applications, new algorithms, and mathematical properties of tensor network state methods for the study of ground states, systems at nonzero temperatures, dynamical response, and non-equilibrium phenomena.

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.
