Instantaneous and dynamical decoherence

, 2018
International audienceTwo manifestations of decoherence, called instantaneous and dynamical, are investigated. The former reflects the suppression of the interference between the components of the current state while the latter reflects that within the ...

Coherence via decoherence

, 2003
In general, decoherence destroys quantum-mechanical interference originating from the coherent superposition of complex probability amplitudes. In this paper we show how decoherence of a quantized electromagnetic field inside a cavity influences atomic

A Flea on Schroedinger's Cat [PDF]

, 2012
We propose a technical reformulation of the measurement problem of quantum mechanics, which is based on the postulate that the final state of a measurement is classical; this accords with experimental practice as well as with Bohr's views.

Collisional model with dissipative and dephasing baths: nonadditive effects at strong coupling

New Journal of Physics
The repeated interaction model provides a framework for emulating and analyzing the dynamics of open quantum systems. We explore here the dynamics generated by this protocol in a system that is simultaneously coupled to two baths through noncommuting ...

Decoherence form space-charge

, 1998
The theory of the Laslett direct space-charge effect is well established since many years. Nevertheless, the fact that transverse coherent tune shifts and decoherence of transverse oscillations have been attributed to direct space-charge, by lack of ...

Decoherence In The Dirac Equation

, 1996
A Dirac particle is represented by a unitarily evolving state vector in a Hilbert space which factors as H spin\Omega H position . Motivated by the similarity to simple models of decoherence consisting of a two state system coupled to an environment ...
