An analytical relation between entropy production and quantum Lyapunov exponents for Gaussian bipartite systems
K. M. Fonseca Romero, J. E. Parreira, L. A. M. Souza +2
We study and compare the information loss of a large class of Gaussian bipartite systems. It includes the usual Caldeira-Leggett type model as well as Anosov models (parametric osc…

Quantum NOT Operation and Integrability in Two-Level Systems
Renato M. Angelo, Walter F. Wreszinski
We demonstrate the surprising integrability of the classical Hamiltonian associated to a spin 1/2 system under periodic external fields. The one-qubit rotations generated by the dy…
