Master-equations for the study of decoherence
arXiv:quant-ph/0301039 · doi:10.1007/s10773-005-7077-4
Abstract
Different structures of master-equation used for the description of decoherence of a microsystem interacting through collisions with a surrounding environment are considered and compared. These results are connected to the general expression of the generator of a quantum dynamical semigroup in presence of translation invariance recently found by Holevo.
