Dissipative exciton dynamics on small networks — •Johannes Kohlberger and Oliver Mülken — Albert-Ludwigs-Universität Freiburg, Germany

Excitation transfer through networks coupled to an environment plays an important role in many areas of physics and biology. We would like to understand the fundamental transport phenomena of different kinds of networks like the Fenna-Matthews-Olson (FMO) complex. For this purpose we consider small networks like dimers and trimers and use different approaches of the Lindblad-Master equation to couple them to an environment. With this approach it is possible to connect the network to different kinds of reservoirs like a trap or a source to get a more realistic coupling from the FMO-complex to the chlorosomes and the reaction centre. The advantage of studying those small networks is, that it is partly possible to solve them analytically and therefore get some fundamental insights in such transport processes, which can be used to understand transport phenomena in larger networks.
