Extension of the Nakajima-Zwanzig approach to multitime correlation functions of open systems
Anton Ivanov, Heinz-Peter Breuer
We extend the Nakajima-Zwanzig projection operator technique to the determination of multitime correlation functions of open quantum systems. The correlation functions are expresse…

Quantum corrections of the truncated Wigner approximation applied to an exciton transport model
Anton Ivanov, Heinz-Peter Breuer
We modify the path integral representation of exciton transport in open quantum systems such that an exact description of the quantum fluctuations around the classical evolution of…
