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…
Dissipation and Decoherence in Mean Field Theory
Salman Habib, Yuval Kluger, Emil Mottola +1
The time evolution of a closed system of mean fields and fluctuations is Hamiltonian, with the canonical variables parameterizing the general time-dependent Gaussian density matrix…
Quantum evolution of the disoriented chiral condensates
Y. Kluger, F. Cooper, E. Mottola +2
We study the dynamics of the chiral phase transition expected during the expansion of the quark-gluon plasma produced in a high energy hadron or heavy ion collision, using the $O(4…
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…
Decoherence, Re-coherence, and the Black Hole Information Paradox
J. R. Anglin, R. Laflamme, W. H. Zurek +1
We analyze a system consisting of an oscillator coupled to a field. With the field traced out as an environment, the oscillator loses coherence on a very short {\it decoherence tim…
Environment--Induced Decoherence, Classicality and Consistency of Quantum Histories
Juan Pablo Paz, Wojciech Hubert Zurek
We prove that for an open system, in the Markovian regime, it is always possible to construct an infinite number of non trivial sets of histories that exactly satisfy the probabili…
