Interaction-induced chaos in a two-electron quantum-dot system
A. J. Fendrik, M. J. Sánchez, P. I. Tamborenea
A quasi-one-dimensional quantum dot containing two interacting electrons is analyzed in search of signatures of chaos. The two-electron energy spectrum is obtained by diagonalizati…
Semiclassical density of degeneracies in quantum regular systems
A. J. Fendrik, M. J. Sánchez
The spectrum of eigenenergies of a quantum integrable system whose hamiltonian depends on a single parameter shows degeneracies (crossings) when the parameter varies. We derive a s…
Persistent currents in mesoscopic cavities and the effect of level crossings as random variables
A. J. Fendrik, M. J. Sanchez
In the present article we perform analytical and numerical calculations related to persistent currents in 2D isolated mesoscopic annular cavities threaded by a magnetic flux. The s…
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…
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…
