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…
Quantum localization measures in phase space
D. Villaseñor, S. Pilatowsky-Cameo, M. A. Bastarrachea-Magnani +2
Measuring the degree of localization of quantum states in phase space is essential for the description of the dynamics and equilibration of quantum systems, but this topic is far f…
Quantum chaos in a system with high degree of symmetries
Javier de la Cruz, Sergio Lerma-Hernandez, Jorge G. Hirsch
We study dynamical signatures of quantum chaos in one of the most relevant models in many-body quantum mechanics, the Bose-Hubbard model, whose high degree of symmetries yields a l…
