Localization of coherent exciton transport in phase space
Oliver Muelken, Veronika Bierbaum, Alexander Blumen
We study numerically the dynamics of excitons on discrete rings in the presence of static disorder. Based on continuous-time quantum walks we compute the time evolution of the Wign…
Coherent dynamics on hierarchical systems
Alexander Blumen, Veronika Bierbaum, Oliver Muelken
We study the coherent transport modeled by continuous-time quantum walks, focussing on hierarchical structures. For these we use Husimi cacti, lattices dual to the dendrimers. We f…
Coherent exciton transport in dendrimers and continuous-time quantum walks
Oliver Muelken, Veronika Bierbaum, Alexander Blumen
We model coherent exciton transport in dendrimers by continuous-time quantum walks (CTQWs). For dendrimers up to the second generation the coherent transport shows perfect recurren…
