Thermalization in the mixed-field Ising model: An occupation number perspective
Isaías 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, Isaías 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
Isaías 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
Isaías 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…
Proposal for many-body quantum chaos detection
Adway Kumar Das, Cameron Cianci, Delmar G. A. Cabral +8
In this work, the term ``quantum chaos'' refers to spectral correlations similar to those found in the random matrix theory. Quantum chaos can be diagnosed through the analysis of…
Self-averaging in many-body quantum systems out of equilibrium: Time dependence of distributions
E. Jonathan Torres-Herrera, Isaías Vallejo-Fabila, Andrei J. Martínez-Mendoza +1
In a disordered system, a quantity is self-averaging when the ratio between its variance for disorder realizations and the square of its mean decreases as the system size increases…
Self-averaging in many-body quantum systems out of equilibrium: Chaotic systems
Mauro Schiulaz, E. Jonathan Torres-Herrera, Francisco Pérez-Bernal +1
Despite its importance to experiments, numerical simulations, and the development of theoretical models, self-averaging in many-body quantum systems out of equilibrium remains unde…
Nonequilibrium quantum dynamics of many-body systems
Lea F. Santos, E. Jonathan Torres-Herrera
We review our results for the dynamics of isolated many-body quantum systems described by one-dimensional spin-1/2 models. We explain how the evolution of these systems depends on…
Extended nonergodic states in disordered many-body quantum systems
E. J. Torres-Herrera, Lea F. Santos
This work supports the existence of extended nonergodic states in the intermediate region between the chaotic (thermal) and the many-body localized phases. These states are identif…
