Starting from a naive perturbative solution of the von Neumann equation, the reduced density matrix with the coarse grained time steps is obtained using the assumption of short correlation time of the bath field. Then applying the renormalization group method, it is shown that dependence of the specific initial time in the solution can be removed and the Markovian semi-group master equation in Lindblad form is attained in the weak coupling limit.", "revisions": [ { "version": "v1", "updated": "2015-04-13T06:09:56.000Z" } ], "analyses": { "keywords": [ "markovian master equation", "derivation", "markovian semi-group master equation", "von neumann equation", "coarse grained time steps" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
