November 29: “Factorization versus chaos in the IKKT matrix model” by Mihailo Čubrović

Date : November 29, 2022, 16:00 CET Mihailo Čubrović (Institute of Physics Belgrade) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Factorization versus chaos in the IKKT matrix model Abstract: I discuss the problem of factorization and its relation to quantum chaos in the framework of Type IIB matrix model (IKKT matrix model). Euclidean partition functions for the fluctuations of D-brane stacks […]

November 22: “Cosmology as a holographic wormhole” by Brian Swingle

Date : November 22, 2022, 16:00 CET Brian Swingle (Brandeis University) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Cosmology as a holographic wormhole Abstract: We argue that standard tools of holography can be used to describe fully non-perturbative microscopic models of cosmology in which a period of accelerated expansion may result from the positive potential energy of time-dependent scalar fields evolving […]

November 15: “Holographic Meissner effect” by Makoto Natsuume

November 15: “Holographic Meissner effect” by Makoto Natsuume

Date : November 15, 2022, 14:00 CET Makoto Natsuume (KEK, Japan) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Holographic Meissner effect Abstract: The holographic superconductor is the holographic dual of superconductivity, but there is no Meissner effect in conventional holographic superconductors. This is because the boundary Maxwell field is added as an external source and is not dynamical. We explain how […]

November 8: “Towards a hydrodynamic theory for condensed matter systems” by Jácome Armas

November 8: “Towards a hydrodynamic theory for condensed matter systems” by Jácome Armas

Date : November 8, 2022, 16:00 CET Jácome Armas (University of Amsterdam ) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Towards a hydrodynamic theory for condensed matter systems Abstract: I will discuss a new hydrodynamic theory that accounts for pinning, phase, and momentum relaxation effects due to translational disorder, diffusion due to the presence of interstitials and vacancies, and strain relaxation […]

November 1: “Relativistic hydrodynamics: a singulant perspective” by Alexandre Serantes

Date : November 1, 2022, 16:00 CET Alexandre Serantes (University of Barcelona) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Relativistic hydrodynamics: a singulant perspective Abstract: The formulation of relativistic hydrodynamics in an effective field theory language rests on a gradient expansion around local thermal equilibrium. Until recently, our understanding of the large-order behavior of this gradient expansion was restricted to two […]

October 25: “Slow modes in non-hydrodynamic regime” by Yi Yin

October 25: “Slow modes in non-hydrodynamic regime” by Yi Yin

Date : October 25, 2022, 16:00 CEST Yi Yin (CAS, China) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Slow modes in non-hydrodynamic regime Abstract: Identifying possible slow modes remains a major challenge in the study of many-body systems in general and the quark–gluon plasma (QGP) produced in heavy-ion collisions in particular. In this talk, I discuss relevent d.o.fs in non-hydrodynamic regime […]

October 18: “Covariant prescriptions for holographic entanglement” by Veronika Hubeny

October 18: “Covariant prescriptions for holographic entanglement” by Veronika Hubeny

Date : October 18, 2022, 18:00 CEST Veronika Hubeny (UC Davis) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Covariant prescriptions for holographic entanglement Abstract: In the holographic setting of gauge/gravity duality, there has been a growing expectation that the emergence of the bulk gravitational spacetime is rooted in the entanglement structure of the dual gauge theory. While the deep connection remains […]

Critical and near-critical relaxation of holographic superfluids

Critical and near-critical relaxation of holographic superfluids

Date : October 11, 2022, 16:30 CEST (unusual time!) Sebastian Grieninger (Stony Brook University) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Critical and near-critical relaxation of holographic superfluids Abstract: We investigate the relaxation of holographic superfluids after quenches with end state is either exactly on the critical point, or very close to it. In the former case the system exhibits a […]

October 4: “Large N fractons” by Kristan Jensen

Date : October 4, 2022, 16:00 CEST Kristan Jensen (University of Victoria) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Large N fractons Abstract: I will discuss some aspects of coarse-grained models of fractons. These theories have been of recent interest to condensed matter and high energy theorists. On the one hand they are candidates for new phases of quantum matter, and […]
