The addition spectrum of a disordered stadium is studied for up to 120 electrons using the self consistent Hartree-Fock approximation for different values of the dimensionless conductance and in the presence and absence of a neutralizing background.

The quantum kicked rotor and the classical kicked rotor are both shown to have truncated Levy distributions in momentum space, when the classical phase space has accelerator modes embedded in a chaotic sea. The survival probability for classical part

We independently examine the case of a spin-$j$ particle interacting with a boson field studied by Finney and Gea-Banacloche. We concentrate on their conclusion that in the case $j=1/2$ the correspondence between the quantum and the semiclassical cas

We show that the modified version of quantum mechanics proposed by Ghirardi et al. [Phys. Rev. A 40 (1990) 78] is virtually equivalent to ordinary quantum mechanics, if a statistical perspective is adopted. However, this does not conflict with the po

A completely deterministic derivation of the Fokker-Planck equation based on a simple 2D map is illustrated. Both friction and diffusion are derived from the properties of the chaotic booster, i.e. the map, with no ad hoc assumptions. Diffusion is sh

We study a two-level quantum system interacting through a coupling strength g with a single-mode radiation field. We show that the rotating-wave-approximation (RWA) Hamiltonian produces quantum-mechanical effects more persistent than those generated

We study the Hamiltonian of a two-level system interacting with a one-mode radiation field by means of the Wigner method and without using the rotating-wave approximation. We show that a phenomenon of collapses and revival, reminiscent of that exhibi
