Quantum signatures and semiclassical limitations in the transmission of Fock states
Daniel Julian Nader
Transmission through potential barriers is a fundamental problem in quantum mechanics. While semiclassical methods can approximate certain aspects of transmission, they fail to cap…
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…
A numerical study of the Bose-Einstein condensates in a double-well trap using finite differences
D. J. Nader, E. Serrano-Ensástiga
Bose-Einstein condensates in a double-well potential contain the essential ingredients to study many-body systems within a rich classical phase-space that includes an unstable poin…
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…
