Quantum Chaos and the Black Body Radiation
Giulio Casati
We discuss a mechanical model which mimics the main features of the radiation matter interaction in the black body problem. The pure classical dynamical evolution, with a simple di…
Emergence of Fermi-Dirac Thermalization in the Quantum Computer Core
Giuliano Benenti, Giulio Casati, Dima L. Shepelyansky
We model an isolated quantum computer as a two-dimensional lattice of qubits (spin halves) with fluctuations in individual qubit energies and residual short-range inter-qubit coupl…
The triangle map: a model of quantum chaos
Giulio Casati, Tomaz Prosen
We study an area preserving parabolic map which emerges from the Poincar\' e map of a billiard particle inside an elongated triangle. We provide numerical evidence that the motion…
Quantum Poincare' recurrences in microwave ionization of Rydberg atoms
Giuliano Benenti, Giulio Casati
We study the time dependence of the ionization probability of Rydberg atoms driven by a microwave field. The quantum survival probability follows the classical one up to the Heisen…
