Semiclassical quantization with short periodic orbits
Eduardo G. Vergini, Gabriel Carlo
We apply a recently developed semiclassical theory of short peridic orbits to the stadium billiard. We give explicit expresions for the resonances of periodic orbits and for the ap…
Semiclassical Theory of Short Periodic Orbits in Quantum Chaos
Eduardo G. Vergini
We have developed a semiclassical theory of short periodic orbits to obtain all quantum information of a bounded chaotic Hamiltonian system. If T_1 is the period of the shortest pe…
Influence of phase space localization on the energy diffusion in a quantum chaotic billiard
D. A. Wisniacki, E. Vergini
The quantum dynamics of a chaotic billiard with moving boundary is considered in this work. We found a shape parameter Hamiltonian expansion which enables us to obtain the spectrum…
Numerical verification of Percival's conjecture in a quantum billiard
Gabriel Carlo, Eduardo Vergini, Alejandro Fendrik
In order to verify Percival's conjecture [J. Phys. B 6,L229 (1973)] we study a planar billiard in its classical and quantum versions. We provide an evaluation of the nearest-neighb…
Localized Structures Embedded in the Eigenfunctions of Chaotic Hamiltonian Systems
E. Vergini, D. A. Wisniacki
We study quantum localization phenomena in chaotic systems with a parameter. The parametric motion of energy levels proceeds without crossing any other and the defined avoided cros…
Quantitative study of scars in the boundary section of the stadium billiard
Fernando P. Simonotti, Eduardo Vergini, Marcos Saraceno
We construct a semiclassically invariant function on the boundary of the billiard, taken as the Poincare section in Birkhoff coordinates, based on periodic orbit information, as an…
Characterization of Landau-Zener Transitions in Systems with Complex Spectra
M. J. Sánchez, E. Vergini, D. A. Wisniacki
This paper is concerned with the study of one-body dissipation effects in idealized models resembling a nucleus. In particular, we study the quantum mechanics of a free particle th…
