Dynamical chaos versus quantum interference
Valentin V. Sokolov, Giuliano Benenti, Giulio Casati
We discuss the dephasing induced by the internal classical chaotic motion in the absence of any external environment. To this end a new extension of fidelity for mixed states is in…
Reversible and irreversible dynamics of a qubit interacting with a small environment
Giuliano Benenti, G. Massimo Palma
We analyze the dynamics of a system qubit interacting by means a sequence of pairwise collisions with an environment consisting of just two qubits. We show that the density operato…
Conservative chaotic map as a model of quantum many-body environment
Davide Rossini, Giuliano Benenti, Giulio Casati
We study the dynamics of the entanglement between two qubits coupled to a common chaotic environment, described by the quantum kicked rotator model. We show that the kicked rotator…
