1	The role of system-environment correlations in the dynamics of open quantum systems Pernice, Ansgar 25 June 2013 (has links) (PDF) In the present thesis the dynamics of the correlations between an open quantum system and its environment is investigated. This becomes feasible by means of a very useful representation of the total system-environment state. General conditions for separability and entanglement of the latter are derived, and investigated in the framework of an open quantum two-level system, which is coupled to a dissipative and a dephasing environment.
