Description

In this talk I will discuss recent developments and applications of Eigenstate Thermalization Hypothesis, the underlying microscopic mechanism explaining thermalization of isolated quantum ergodic systems. I will start with a brief review of the subject in case of many-body quantum systems and then formulate the hypothesis for the conformal field theories. In the second part of the talk I will discuss the connection between Eigenstate Thermalization and Random Matrix Theory and will argue that thermalization of quantum systems involves a new timescale, which is parametrically longer than Thouless time. The talk is based on arXiv:1804.08626, arXiv:1710.10458, arXiv:1610.00302.
