Abstract
Quantum mechanics describes the unitary time evolution of isolated systems. In reality, every quantum system interacts with its environment, leading to an irreversible loss of the phase relation. Path integral based methods provide a rigorous description of the process of decoherence. We provide an overview over recent numerical methods suited to describe the non-perturbative regime of system bath interaction. - Quantenmechanik beschreibt die unitäre Zeitentwicklung isolierter Systeme. In der Realität interagiert jedes Quantensystem mit seiner Umwelt, was zu einem irreversiblen Verlust von Phasenbeziehungen führt. Pfadintegralbasierte Methoden erlauben eine rigorose Beschreibung dieser Dekohärenzprozesse.
