Decoherence in Quantum Brownian Motion

General Relativity and Quantum Cosmology 2007-05-23 v1 High Energy Physics - Theory

Abstract

We examine the dependence of decoherence on the spectral density of the environment as well as on the initial state of the system. We use two simple examples to illustrate some important effects. The simplest derivation of the general form of the master equation for a general quantum Brownian motion is outlined in an Appendix.
