May 28 – September 17
Physicists are encouraged to apply as individual researchers to work on their own projects at the Aspen Center for Physics for up to five weeks at any time during the summer. We provide a serene atmosphere to complete work. The individual researcher may also choose to attend any workshop meetings or chat with other scientists in residence in addition to working on his or her own research.

There is a gap in our understanding of the period between the end of inflation and the production of the light elements. While the inflationary paradigm provides a consistent, calculable framework for understanding the origin of structure in our universe, we do not understand the details of how inflation ends and how we arrive at a universe with thermalized SM (and beyond SM) components. The detailed mechanisms for generating stable relics, such as dark matter, or generating the observed matter/antimatter asymmetry continue to elude us. The aim of the proposed workshop is to bring together experts in inflation and reheating, non-perturbative field dynamics and high energy particle physics phenomenology, as well as observers interested in exploring and constraining this rich period in our cosmic history.
May 28 - June 18
In very recent years, the subject of Moonshine has made unexpected appearances in various corners of string theory, and most remarkably in the physics of black holes and lower dimensional gravity. This is leading to an avalanche of ``New Moonshine Conjectures'', which raises a multitude of open problems, and in our opinion the time is ripe to tackle them. Answers to these questions will deepen our understanding of conformal field theory, the string theory landscape, black holes and other aspects of quantum gravity.
June 4 - June 25
Quantum information theory is playing an increasingly
important role in our understanding of fundamental properties of quantum field theory and quantum gravity. When combined with the local nature of interactions, information theory often leads to surprising and nontrivial results. The holographic correspondence further extends the reach of information theory to the realm of quantum gravity. This workshop will focus on applications of information theory to field theoretic systems, encompassing a wide range of topics fundamental to high energy theory, gravitational physics, and condensed matter. Among the areas of particular interest are:
June 11 - July 2
Packing problems have been at the core physical descriptions of matter dating back to at least the time of Kepler. This workshop will bring together researchers from diverse fields working to understand packing of filaments and sheets in three-dimensional space. In comparison to problems of packing compact and rigid elements, the consequences of the more subtle interplay between shape and separation of continuously deformable, extended objects on their space-filling arrangements and collective behaviors at high density are far less understood. And this, despite the diverse applications of filament and sheet packing problems to current challenges in biology and materials science, from the fractal packing of condensed chromosomes to the design of 2D metamaterials. The scope of the workshop will cover recent advances in characterizing, understanding and optimizing multi-filament/sheet assemblies, as well as frontier questions stemming from new observations and emerging challenges in biological and synthetic matter.
June 18 - July 9
Neutron star physics is at a very fertile moment, with remarkable and ongoing progress from both observational and theoretical directions. The importance of understanding their behavior and structure has been underlined by the recent direct detection of gravitational radiation, since neutron stars mergers with black holes or neutron stars will be principal sources of future observations of gravitational waves. Direct observation of 2.0 solar mass stars and ongoing determinations of masses and radii are constraining the composition of neutron star interiors; the NICER experiment, soon to be delivered to the International Space Station, will provide a wealth of new data. At the same time, an emerging understanding in quantum chromodynamics (QCD) of how nuclear matter turns into deconfined quark matter at high baryon densities, has led to advances in understanding the equation of state of the matter under the extreme conditions in neutron star interiors, work complementary to studies of dense matter at ultrarelativistic heavy ion collision experiments at RHIC in Brookhaven and the LHC at CERN. The aim of this workshop is to bring together researchers from the various disciplines involved in these advances -- including observers of pulsars and compact X-ray sources, nuclear and QCD physicists studying dense matter, and gravitational wave physicists – to further advance understanding of neutron star interiors both microscopically and as constrained by observations.

In recent years there has been resurgence of interest in the problem of quantum criticality of metals, which fundamentally challenges our understanding of electronic behavior at the quantum level. A confluence of new developments on the experimental front, driven by new experimental techniques and the discovery of new materials appears to pose more questions than answers. This workshop will address the outstanding problems of quantum-critical behavior in systems with Fermi surfaces and in systems with low-energy excitations around particular points in momentum space, such as graphene and Weyl semi-metals. Materials of interest include heavy fermion metals, cuprates, iron based superconductors and other strongly correlated systems. In these systems the Landau Fermi liquid paradigm breaks down at criticality and there is no natural small parameter for a conventional perturbative expansion. A number of non-perturbative schemes have been proposed, such as the 1/N expansion, dimensional regularization, self-consistent strong coupling treatment. The workshop will offer a forum for assessments of the current state of the art in the understanding of quantum-critical and non-Fermi liquid behavior in metals, identifying the outstanding unsolved problems, and the most promising directions for new theoretical research in this field.
August 20 - September 17
The aim of this workshop is to bring together a group of physicists, engineers, and biologists to discuss the physics of biological and soft
matter systems far from equilibrium. Our primary goal is to identify the
key experimental and theoretical challenges to uncovering the principles
of collective non-equilibrium dynamics in biological systems, from the
intracellular to the organism scale. The major themes of the workshop

Vorticity is encountered in nearly all areas of science – and on an astonishing range of scales. It is encountered in Bose-Einstein condensates, biofluids and biolocomotions, boundary layers, fusion reactors, planetary atmospheres, oceans and climates, stellar and galactic flows, as well as the early Universe. Yet, the viewpoints, analysis tools, and applications of vorticity in all of these areas are rarely compared and contrasted among the different communities. A more global perspective and generalized ‘vorticity thinking’ can be of tremendous mutual benefit: such thinking has already revolutionized understanding in many aspects of modern atmosphere and ocean dynamics and is starting to make significant inroads in plasma physics and astrophysics. In view of this, this workshop will bring together leading researchers of vorticity from different areas of physics. The aim is to provide an opportunity to: i) share the latest research findings and tools in a focused way, ii) stimulate innovative ideas and collaborations, and iii) set new research directions.
