✦ Synopsis

We analyze the coherent dynamics of excitons in three-dimensional topologically disordered networks with traps. If the interactions between the nodes of the network are long ranged, i.e., algebraically decaying as a function of the distance between the nodes, the average survival probability of an exciton surprisingly shows a characteristic decay with features similar to the decay found for regular onedimensional systems. We further show how this decay can be related to the eigenstates of the same system without a trap.
