Thermalization in the mixed-field Ising model: An occupation number perspective
IsaÃas Vallejo-Fabila, Fausto Borgonovi, Felix M. Izrailev +1
The occupation number is a key observable for diagnosing thermalization, as it connects directly to standard statistical laws such as Fermi--Dirac, Bose--Einstein, and Boltzmann di…
Dynamical detection of extended nonergodic states in many-body quantum systems
David A. Zarate-Herrada, IsaÃas Vallejo-Fabila, Lea F. Santos +1
Fractal dimensions are tools for probing the structure of quantum states and identifying whether they are localized or delocalized in a given basis. These quantities are commonly e…
Proposal for many-body quantum chaos detection with single-site measurements
IsaÃas Vallejo-Fabila, Adway Kumar Das, Sayan Choudhury +1
We demonstrate that the long-time dynamics of an observable associated with a single lattice site is sufficient to determine whether a many-body quantum system exhibits level stati…
Timescales for thermalization, quantum chaos, and self-averaging
IsaÃas Vallejo-Fabila, Lea F. Santos
This chapter discusses the conditions and timescales under which isolated many-body quantum systems, initially far from equilibrium, ultimately reach thermal equilibrium. We also e…
Reducing dynamical fluctuations and enforcing self-averaging by opening many-body quantum systems
Isaias Vallejo-Fabila, Adway Kumar-Das, David A. Zarate-Herrada +3
We investigate how the dynamical fluctuations of many-body quantum systems out of equilibrium can be mitigated when they are opened to a dephasing environment. We consider the surv…
