I will discuss recent work on a Hayden & Preskill like setup for both maximally chaotic and sub- maximally chaotic quantum field theories. I will discuss computations of various quantum information measures on the boundary that tell us when a...

In an ordinary quantum field theory, the "split property" implies that the state of a system can be specified independently on a bounded subregion of a Cauchy slice and its complement. This property does not hold for theories of gravity. It can be...

New kinds of vortex sheets with vorticity confined to the boundary layer are proposed and investigated in detail. Exact solutions of the steady Navier-Stokes equations for a planar vortex sheet in arbitrary background strain are found in terms of...

A binary code is simply any subset of 0/1 strings of a fixed length. Given two strings, a standard way of defining their distance is by counting the number of positions in which they disagree. Roughly speaking, if elements of a code are sufficiently...

In this talk I will discuss models of two-dimensional gravity that resolve the factorization puzzle and have a discrete spectrum, whilst retaining a semiclassical description. A novelty of these models is that they contain non-trivially correlated...

We present our studies on the late-time von Neumann entropy and its transition in Brownian SYK models. Without measurement, we show that the correlations between different replicas account for the Page curve at late time, and a permutation group...
