DESCRIPTION:Speaker: Shoki Sugimoto\nhosted by Laszlo Erdös\nAbstract: The
  eigenstate thermalization hypothesis\, which states that the eigenstates 
 of quantum many-body Hamiltonians are in thermal equilibrium by themselves
 \, is considered to be the primary mechanism behind the relaxation of isol
 ated quantum systems to a thermal equilibrium under a unitary time evoluti
 on.  A mathematical argument based on ''typicality'' is proposed to justi
 fy the ETH\, but it is shown that this result cannot justify the ETH in re
 alistic situations with the locality of interactions because almost all Ha
 miltonians considered in that argument contain highly non-local and too-ma
 ny-body correlations.In this talk\, we numerically verify that the eigenst
 ate thermalization hypothesis typically holds even with the locality of in
 teractions while the fraction of systems which does not satisfy the hypoth
 esis is significantly larger than that proposed before.
