Quantum Transport on One-Dimensional Networks with Long-Range Interactions

Hansastr. 9a
In this thesis the continuous-time quantum walk approach is applied to investigate the quantum transport of excitons on discrete structures and compared to the behaviour of classical particles described by the continuous-time random walk. The focus lies on quantities which characterise the transport properties of the network as a whole. In particular the effects of modifications to one-dimensional infinite systems with nearest-neighbour interactions are investigated. As exemplary systems, small-world networks and networks with long-range interactions with and without traps are considered in detail. Significant differences between classical and quantum mechanical transport behaviour are extracted and analysed.
The talk is open to the public. Guests are cordially invited!
