Resonance Assisted Tunneling in Floquet spin-J systems
J. A. Segura-Landa, Diego A. Wisniacki, Sergio Lerma-Hernández +1
We apply the theory of Resonance Assisted Tunneling (RAT) to a many-body quantum kicked system with a well-defined semiclassical limit. Using a quantum resonant condition, we ident…

Resonant fragility and nonresonant robustness of Floquet eigenstates in kicked spin systems
Jesús A. Segura-Landa, Meenu Kumari, Daniel J. Nader +3
In classical systems, the Kolmogorov-Arnold-Moser (KAM) theorem establishes that resonant tori of integrable Hamiltonians are destroyed by any nonintegrable perturbation, whereas n…

The Weakly Bound States in Gaussian Wells: From the Binding Energy of Deuteron to the Electronic Structure of Quantum Dots
G. Rodriguez-Espejo, J. Segura-Landa, J. Ortiz-Monfil +1
Gaussian potentials serve as a valuable tool for the comprehensive modeling of short-range interactions, spanning applications from nuclear physics to the artificial confinement of…
