Dynamical irreversibility and local decoherence in quantum many-body chaos
Jose Alfredo de Leon, Miguel Gonzalez, Carlos Diaz-Mejia
Typical dynamical quantum chaos probes are initial-state dependent (e.g., local observables or purities) and thus may fail to capture typical decoherent behavior one expects of a s…

Dynamical witnesses and universal behavior across chaos and non-ergodicity in the tilted Bose-Hubbard model
Carlos Diaz-Mejia, Sergio Lerma-Hernandez, Jorge G. Hirsch
Quantum chaos in isolated quantum systems is intimately linked to thermalization and the rapid relaxation of observables. Although the spectral properties of the chaotic phase in t…

Diagnosing Thermalization via Participation Ratio in Disordered Bosonic Chains
Javier de la Cruz, Carlos Diaz-Mejia, Sergio Lerma-Hernandez +1
We study thermalization in a disordered one-dimensional interacting bosonic system described by the Aubry-Andre model using full exact diagonalization. We find a broad chaotic ener…
