Energy Transfer and Decoherence in Phase Space — •Per Liebermann1,2 and Oliver Mülken2 — 1Universität des Saarlandes, Saarbrücken, Germany — 2Albert-Ludwigs-Universität Freiburg, Germany
Phase space methods can be used to describe both classical and quantum mechancal transport processes, such as, for instance, the energy transfer in photosynthetic light harvesting complexes. To gain a deeper insight into the phase space dynamics of the Continuous-Time Quantum Walk on a discrete network, a discrete Wigner function represents the quantum state of the system. Environmental effects such as decoherence are implemented in the framework of the Lindblad Master Equation. In this context, the Quantum Stochastic Walk contains the Random Walk and the Quantum Walk as special cases for both strong and weak coupling strengths. Furthermore a source and a drain are added to the trimer's network, leading to a simplified model for the excitation transport within the Fenna-Matthews-Olsen complex.
