Equilibration time in many-body quantum systems
Lezama, Talía L. M.; Torres Herrera, E. Jonathan; Pérez Bernal, Francisco
; Bar Lev, Yevgeny; Santos, Lea F. (American Physical Society, 2021)
Isolated many-body quantum systems quenched far from equilibrium can eventually equilibrate, but it is not yet clear how long they take to do so. To answer this question, we use exact numerical methods and analyze the ... -
Self-averaging in many-body quantum systems out of equilibrium. II. Approach to the localized phase
Torres Herrera, E. Jonathan; De Tomasi, Giuseppe; Schiulaz, Mauro; Pérez Bernal, Francisco; Santos, Lea F. (American Physical Society, 2020)
The self-averaging behavior of interacting many-body quantum systems has been mostly studied at equilibrium. The present paper addresses what happens out of equilibrium, as the increase of the strength of on-site disorder ... -
Self-averaging in many-body quantum systems out of equilibrium: Chaotic systems
Schiulaz, Mauro; Torres Herrera, E. Jonathan; Pérez Bernal, Francisco; Santos, Lea F. (American Physical Society, 2020)
Despite its importance to experiments, numerical simulations, and the development of theoretical models, self-averaging in many-body quantum systems out of equilibrium remains underinvestigated. Usually, in the chaotic ... -
Speck of chaos
Santos, Lea F.; Pérez Bernal, Francisco; Torres Herrera, E. Jonathan (American Physical Society, 2020-10)
It has been shown that, despite being local, a perturbation applied to a single site of the one-dimensional XXZ model is enough to bring this interacting integrable spin-1/2 system to the chaotic regime. Here, we show ...
