Diffusive behavior from a quantum master equation
Diffusive behavior from a quantum master equation
We study a general class of translation invariant quantum Markov evolutions for a particle on \documentclass[12pt]{minimal}\begin{document}${\mathbb Z}^d$\end{document}Zd. The evolution consists of free flow, interrupted by scattering events. We assume spatial locality of the scattering events and exponentially fast relaxation of the momentum distribution. It is shown that the particle position …
