Semiclassical simulation of open quantum systems — •Florian Mintert1,2 and Eric Heller2 — 1Albert-Ludwigs-Universität Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg — 2Department of Physics, Harvard University, 17 Oxford Street, Cambridge, MA 02138, USA
We present an approach for the semiclassical treatment of open quantum systems. An expansion into localized states allows to restrict a simulation to a fraction of the environment that is located within a predefined vicinity of the system. Our approach allows to add and drop environmental particles during the simulation what provides the basis for an effective reduction of the size of the system that is being treated.
