Decoherence and the Loschmidt echo
F. M. Cucchietti, D. A. R. Dalvit, J. P. Paz +1
Environment--induced decoherence causes entropy increase. It can be quantified using, e.g., the purity . When the Hamiltonian of a quantum system is perturbed, its s…

Quantum chaos: a decoherent definition.
W. H. Zurek, J. P. Paz
We show that the rate of increase of von Neumann entropy computed from the reduced density matrix of an open quantum system is an excellent indicator of the dynamical behavior of i…
