Participation Ratio as a Quantum Probe of Hierarchical Stickiness
Ariel A. Galindo Duque, Miguel A. Prado Reynoso, Miguel Gonzalez +1
We investigate how quantum localization encodes the hierarchical stickiness that governs transport in mixed classical phase spaces. Using the periodically driven kicked top, we sho…

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…
