John Chalker: Many-body quantum chaos: insights from random quantum circuits

Abstract

I will give an overview of recent work on quantum dynamics in many-body systems that uses a class of minimal models known as random quantum circuits. This work is concerned with behaviour in quantum systems that are generic, in the sense of having few or no local conservation laws, and are in a highly excited state, so that there is no simple quasiparticle description. While research in this area began many decades ago with the study of spectra in nuclear physics, interesting new insights have come in the past few years from considering these minimal models for spatially extended systems and from examining the dynamics of quantum information.
