The Markov approximation revisited: Inconsistency of the standard quantum Brownian motion model
arXiv:quant-ph/9909051 · doi:10.1016/S0375-9601(98)00940-2
Abstract
We revisit the Markov approximation necessary to derive ordinary Brownian motion from a model widely adopted in literature for this specific purpose. We show that this leads to internal inconsistencies, thereby implying that further search for a more satisfactory model is required.
