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…
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…
Classical and quantum decay of one dimensional finite wells with oscillating walls
A. J. Fendrik, D. A. Wisniacki
To study the time decay laws (tdl) of quasibounded hamiltonian systems we have considered two finite potential wells with oscillating walls filled by non interacting particles. We…
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…
