Probe Signatures of Quantum Chaos with Quantum Sensing
Isaías Vallejo-Fabila, Jing Yang
The spectral form factor (SFF), which is the Fourier transform of the two-point spectral correlation, is a fundamental diagnostics of quantum chaos. Nevertheless, its experimental…
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…
Late-time universal distribution functions of observables in one-dimensional many-body quantum systems
I. Vallejo-Fabila, E. Jonathan Torres-Herrera
We study the probability distribution function of the long-time values of observables being time-evolved by Hamiltonians modeling clean and disordered one-dimensional chains of man…
Effects of auto-correlated disorder on the dynamics in the vicinity of the many-body localization transition
Isaías Vallejo-Fabila, E. Jonathan Torres-Herrera
The presence of frozen uncorrelated random on-site potential in interacting quantum systems can induce a transition from an ergodic phase to a localized one, the so-called many-bod…
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…
