The goal of the project is to describe and to understand the equilibration dynamics of a system proper in contact with a heat bath on the wavefunction level using a semiclassical formulation of the quantum dynamics of the (finite) composite system. We will focus on systems of continuous variables where, in contrast to spin systems, every single degree of freedom already has an infinitely large Hilbert space. Using the time-dependent semiclassical (hybrid) approach, composite systems with more than 100 degrees of freedom can and will be treated explicitely. Different well established measures will allow to investigate the time scale of the equilibration dynamics and its dependence on system size.
