DESCRIPTION:Spreading of correlations in Hermitian and non-Hermitian quantu
 m systemsDespres Julien (LPTMS - Collège de France)During this presentati
 on\, I will give you an overview of one part of my research work done duri
 ng my PhD and my postdoc concerning the spreading of correlations in isola
 ted quantum systems governed by a Hermitian or a non-Hermitian Hamiltonian
 . For the Hermitian case\, I will introduce a generic form of the equal-ti
 me correlation function found using a quasiparticle picture which is valid
  for a large number of quantum systems. From the latter\, I will extract t
 he scaling laws of the correlation edge also called Lieb-Robinson bound de
 pending if short-range or long-range interactions are considered. For the 
 non-Hermitian case\, I will present several results concerning the spreadi
 ng of correlations for the non-Hermitian short-range Ising model.
