SUMMARY:Thermalization and many-body localization in disordered quantum sys
	tems
DESCRIPTION:Featuring Maksym Serbyn\, UC Berkeley\n\nPart of the Condensed 
	Matter Theory Seminar Series.\n\nAbstract: Statistical mechanics relies on 
	thermalization assumption in an essential way. But do all isolated quantum 
	many-body systems work as their own heat bath and thermalize? Surprisingly\
	, the answer is no: recently\, it was found that there is a class of so cal
	led many-body localized systems which fail to thermalize. Many-body localiz
	ation in particular arises in the presence of strong disorder\, which const
	rains quantum dynamics. In this talk I will argue that MBL phase exhibits a
	 new kind of integrability\, being characterized by the emergence of a comp
	lete set of quasi-local integrals of motion. Unlike previously known exampl
	es\, the integrability of MBL phase does not rely on symmetries and is robu
	st with respect to perturbations. I will build a universal description of M
	BL phase\, and use it to predict the universal power-law relaxation in a qu
	antum quench experiments. In the second part of the talk\, I will describe 
	a new approach to MBL-delocalization transition. I will introduce a many-bo
	dy generalization of Thouless conductance which probes the response of the 
	system to local perturbations\, and allows to locate the many-body mobility
	 edge. I will conclude with an outlook of future directions in studying non
	-equilibrium properties of interacting quantum systems.
