Integrable, Mixed, and Chaotic Dynamics in a Single All-to-All Ising Spin Model
David Amaro-Alcalá, Carlos Pineda
We demonstrate that the Ising all-to-all (ATA) model exhibits a range of dynamics, from integrable to chaotic, including mixed behaviour across symmetry blocks within a single syst…

Exploring quantum ergodicity of unitary evolution through the Krylov approach
Gastón F. Scialchi, Augusto J. Roncaglia, Carlos Pineda +1
In recent years, there has been growing interest in characterizing the complexity of quantum evolutions of interacting many-body systems. When a time-independent Hamiltonian govern…
