DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QM3/16/">Eig
 enstate Thermalization\, random matrices and (non)local operators in many-
 body systems</a>\nby Masud Haque (Maynooth University) as part of Quantum 
 Matter meets Maths (IST\, Lisbon)\n\n\nAbstract\nThe eigenstate thermaliza
 tion hypothesis (ETH) is a cornerstone in our understanding of quantum sta
 tistical mechanics. The extent to which ETH holds for nonlocal operators (
 observables) is an open question. I will address this question using an an
 alogy with random matrix theory. The starting point will be the constructi
 on of extremely non-local operators\, which we call Behemoth operators. Th
 e Behemoths turn out to be building blocks for all physical operators. Thi
 s construction allow us to derive scalings for both local operators and di
 fferent kinds of nonlocal operators.\n
