Fidelity decay in interacting two-level boson systems: Freezing and revivals
Luis Benet, Saúl Hernández-Quiroz, Thomas H. Seligman
We study the fidelity decay in the -body embedded ensembles of random matrices for bosons distributed in two single-particle states, considering the reference or unperturbed Ham…
Nearest-Neighbor Distributions and Tunneling Splittings in Interacting Many-Body Two-Level Boson Systems
Saúl Hernández-Quiroz, Luis Benet
We study the nearest-neighbor distributions of the -body embedded ensembles of random matrices for bosons distributed over two-degenerate single-particle states. This ensemb…
Scattering off an oscillating target: Basic mechanisms and their impact on cross sections
I. Brouzos, A. K. Karlis, C. A. Chrysanthakopoulos +4
We investigate classical scattering off a harmonically oscillating target in two spatial dimensions. The shape of the scatterer is assumed to have a boundary which is locally conve…
Phase-Space Volume of Regions of Trapped Motion: Multiple Ring Components and Arcs
L. Benet, O. Merlo
The phase--space volume of regions of regular or trapped motion, for bounded or scattering systems with two degrees of freedom respectively, displays universal properties. In parti…
Multiple Components in Narrow Planetary Rings
L. Benet, O. Merlo
The phase-space volume of regions of regular or trapped motion, for bounded or scattering systems with two degrees of freedom respectively, displays universal properties. In partic…
Phase-Space Structure for Narrow Planetary Rings
L. Benet, O. Merlo
We address the occurrence of narrow planetary rings under the interaction with shepherds. Our approach is based on a Hamiltonian framework of non-interacting particles where open m…
