Description
Quantum systems interacting with surrounding reservoirs are of fundamental interest in atomic, molecular, and condensed matter physics. Due to the impressive experimental progress in tailoring and controlling quantum devices on nano- and microscales, theory is challenged to provide a detailed understanding of the nonequilibrum dynamics also in presence of external forces.
A formally exact description is based on path integrals which can efficiently been evaluated with corresponding MC techniques. These have been substantially
improved in the last decade to capture interactions with bosonic as well as fermionic reservoirs. In this talk I will describe the main challenges, numerical techniques, and typical applications.
