Stochastic Schrödinger equation and quantum-classical dynamics — •Wolfgang Pfersich and Walter T. Strunz — Fakultät für Mathematik und Physik, Albert-Ludwigs-Universität Freiburg, Hermann-Herder-Str.3, 79104 Freiburg

We develop a framework to derive non-Markovian stochastic Schrödinger equations for open quantum systems in any order of the coupling strength to the environment. The derivation is based on Heisenberg’s equation of motion using the coherent state representation for the environmental degrees of freedom. It is further shown that this framework allows us to derive consistent time evolution equations for coupled quantum-classical dynamics. These may be applied to nonlinear baths and couplings.
