Time-evolution of local information : thermalization dynamics of local observables (Loïc Herviou / LPT / Seminar). – 3/12, 11H.

3 December 2021; 11h00 - 12h30

Loïc Herviou (EPFL, Lausanne)

Abstract : Understanding thermalization in closed quantum mechanics remains a subtle problem. As the occupancies of the Hamiltonian eigenstates are conserved, thermalization occurs when eigenstates close in energy share similar local observables. In this talk, I will discuss thermalization through the point of view of information. I will introduce a concept of information lattice, which allows to represent the information flow using locality as an additional dimension. Thermalization then corresponds to a flow of the state specific information to a non-local range. Based on this observation, I will propose a tentative algorithm that allows to simulate large scale dissipative systems at long times.
