Quantum Darwinism in quantum Brownian motion.
Quantum Darwinism--the redundant encoding of information about a decohering system in its environment--was proposed to reconcile the quantum nature of our Universe with apparent classicality. We report the first study of the dynamics of quantum Darwinism in a realistic model of decoherence, quantum Brownian motion. Prepared in a highly squeezed state--a macroscopic superposition--the system lea...
متن کاملDecoherence in Quantum Brownian Motion
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.
متن کاملUniversality of quantum Brownian motion
Are Markovian master equations for quantum Brownian motion independent of model assumptions used in the derivation and, thus, universal? With the aim of answering this question, we use a random band–matrix model for the system–bath interaction to derive Markovian master equations for the time evolution of one– dimensional quantum systems weakly coupled to a heat bath. We study in detail two sim...

متن کاملQuantum Trajectories for Brownian Motion
We present the stochastic Schrödinger equation for the dynamics of a quantum particle coupled to a high temperature environment and apply it to the dynamics of a driven, damped, nonlinear quantum oscillator. Apart from an initial slip on the environmental memory time scale, in the mean, our result recovers the solution of the known non-Lindblad quantum Brownian motion master equation. A remarka...
