Abstract

The microscopic derivation of Open Quantum Brownian Motion (OQBM) is presented [1,2]. OQBM is obtained as a special limit (scaling limit) of the recently introduced Open Quantum Walks [3,4]. The quantum master equation for OQBM is derived for a weakly driven system interacting with the decoherent environment. Examples of the dynamics for initial Gaussian and non-Gaussian distributions are presented. [1] M. Bauer, D. Bernard and A. Tilloy, Phys. Rev. A 88 (2013), 062340. [2] M. Bauer, D. Bernard and A.
