Formal features of a General Theoretical Framework for Decoherence in open and closed systems
(Springer/plenum Publishers, 2013-05)
Two complementary decoherence formalisms, Environment Induced Decoherence (EID) for open systems and Self Induced Decoherence (SID) for close systems are compared under a common General Theoretical Formalism for Decoherence ...
Self-induced decoherence and the classical limit of quantum mechanics
(University of Chicago Press, 2005-12)
In this paper we argue that the emergence of the classical world from the underlying quantum reality involves two elements: self‐induced decoherence and macroscopicity. Self‐induced decoherence does not require the openness ...
The problem of the classical limit of quantum mechanics and the role of self-induced decoherence
Our account of the problem of the classical limit of quantum mechanics involves two elements. The first one is self-induced decoherence, conceived as a process that depends on the own dynamics of a closed quantum system ...
Decoherence of domains and defects at phase transitions
(Elsevier Science, 2007-04)
In this further Letter on the onset of classical behaviour in field theory due to a phase transition, we show that it can be phrased easily in terms of the decoherence functional, without having to use the master equation. ...
Decoherence from qubit-qubit dipolar interaction in an all silicon quantum computer

Predicting decoherence in discrete models
(Springer/plenum Publishers, 2011-06)
The general aim of this paper is to supply a method to decide whether a discrete system decoheres or not, and under what conditions decoherence occurs, with no need of appealing to computer simulations to obtain the time ...
Decoherence and loss of entanglement in acoustic black holes
(American Physical Society, 2012-06)
We study the process of decoherence in acoustic black holes. We focus on the ion trap model proposed by Horstmann et al., but the formalism is general to any experimental implementation. For that particular setup, we compute ...
Redundancy of classical and quantum correlations during decoherence
(American Physical Society, 2009-10)
We analyze the time dependence of entanglement and total correlations between a system and fractions of its environment in the course of decoherence. For the quantum Brownian motion model, we show that the entanglement and ...
The Lee Friedrichs model: continuous limit and decoherence
(Springer/plenum Publishers, 2007-12)
We analyze the thermodynamic limit of the Hamiltonian, states and observables, of a system containing an oscillator interacting with a thermal bath We use the results to a compare environment and self induced decoherence.
