Advances and Challenges in Computational Relativity Virtual Workshop
14. Sep 2020 - 18. Sep 2020 • Providence RI - Virtual Workshop, Vereinigte Staaten
Veranstalter:
ICERM
Zusammenfassung:
Virtual Workshop. This kick-off workshop will seek to provide an overview of both the state-of-the-art and open challenges drawing from multiple themes (theory, analysis of the equations, computation, and data analysis) within the broad context of Einstein’s general relativity theory. The workshop will also feature a code bootcamp on the last day. The bootcamp participants will be given both an overview of the key pieces of software used in the field as well as practical instructions on installing and running example cases.

Mathematical and Computational Approaches for Solving the Source- Free Einstein Field Equations Virtual Workshop
05. Okt 2020 - 09. Okt 2020 • Providence RI - Virtual Workshop, Vereinigte Staaten
Veranstalter:
ICERM
Zusammenfassung:
This workshop will focus on theoretical and computational approaches to solving the vacuum Einstein field equations (the master equation of general relativity: a nonlinear, coupled, hyperbolic-elliptic PDE system) without matter field sources. A particular important special case is the simulation of two merging black holes, which will be emphasized throughout the workshop. Gravitational wave solutions will be another important aspect of this workshop, and special attention will be given to modeling techniques for the computation of these waves. The topics covered in this workshop will be relevant to both LIGO and LISA scientific efforts.

Mathematical and Computational Approaches for the Einstein Field Equations with Matter Fields Virtual Workshop
26. Okt 2020 - 30. Okt 2020 • Providence RI - Virtual Workshop, Vereinigte Staaten
Veranstalter:
ICERM
Zusammenfassung:
This workshop will focus on theoretical and computational approaches to solving the Einstein field equations (the master equation of general relativity: a nonlinear, coupled, hyperbolic-elliptic PDE system) with (fluid) matter field sources, as typical of binary neutron stars and supernovae. Simulations of these systems are targets of interest to both LIGO and telescopes such as Hubble, Fermi, and CHANDRA. In this workshop, special attention will be given to the governing equations of relativistic (magneto- ) hydrodynamics and multi-scale, multi-physics modeling challenges.

Statistical Methods for the Detection, Classification, and Inference of Relativistic Objects Virtual Workshop
16. Nov 2020 - 20. Nov 2020 • Providence RI - Virtual Workshop, Vereinigte Staaten
Veranstalter:
ICERM
Zusammenfassung:
This workshop will focus on data analysis strategies for comparing model predictions to data. Special attention will be placed on comparing solutions to the Einstein field equations (as in workshops 2 and 3) with data collected from gravitational-wave or telescopes. The workshop will include (but will not be limited to) coverage of topics involving reduced-order models, surrogate models, machine learning, UQ, and Bayesian techniques.

The Physics of Modularity
01. Dez 2020 - 04. Dez 2020 • UC Santa Barbara, Vereinigte Staaten
Veranstalter:
Kavli Institute for Theoretical Physics (KITP)
Zusammenfassung:
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.
Themen:
new moonshines and mock modular forms; vertex operator algebras arising in supersymmetric gauge theories; topological invariants of 3- and 4-manifolds; topological QFTs and topological phases in condensed matter physics; topological string theory, Donaldson-Thomas theory, and enumerative geometry; scattering amplitudes in string theory; 2d conformal field theories, the modular bootstrap, and connections to 3d quantum gravity

Is There a Common Thread to Layering in Atmospheres, Oceans and Plasmas?
05. Jan 2021 - 08. Jan 2021 • UC Santa Barbara, Vereinigte Staaten
Veranstalter:
Kavli Institute for Theoretical Physics (KITP)
Zusammenfassung:
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.
