We employ the AdS/BCFT construction to describe a gravity dual of moving mirrors. We will show that the […]

Maryland) Link: https://zoom.us/j/98810153463?pwd=WWtWQXBURGw1NTZ2Rm82QThPbW42dz09 Title: Quantum Gravity in the Lab Abstract: I will describe the quantum gravity in the lab program and argue that it offers the possibility of using quantum simulators and quantum computers to study the non-perturbative dynamics of quantum gravity in so far inaccessible regimes. Moreover, even if such simulations are still many years away, I will argue that […]

Abstract: Whether, how, and to what extent solutions of Bjorken-expanding systems become insensitive to aspects of their initial conditions is of importance for heavy-ion collisions. In this talk I will present attractor solutions in hydrodynamics, kinetic theory and holography, […]

In this talk, we focus on the pole skipping phenomenon in non-maximally chaotic theories. Our discussion is informed by results from […]

This is either a Galilean boost symmetry or a Lorentzian one and leads to the Navier-Stokes equations or their relativistic counterpart. It is […]

One of these technicalities is that for many […]

We provide a unifi​ed view of assigning a cost to circuits based on the […]

In contrast to the standard method of Shenker […]

AC transport in these models has a few interesting features, which were in […]
