A Monte Carlo approach for the real time dynamics of tunneling systems in condensed phases

A Monte Carlo method for evaluating real time path integrals is proposed. We study two-level tunneling systems coupled to many body environments. A dynamical correlation function for a model of quantum coherence shows a plateau indicative of the localization effects of damping.
