Slow Excitation Trapping in Quantum Transport with Long-Range Interactions
arXiv:0804.4117 · doi:10.1103/PhysRevE.78.021115
Abstract
Long-range interactions slow down the excitation trapping in quantum transport processes on a one-dimensional chain with traps at both ends. This is counter intuitive and in contrast to the corresponding classical processes with long-range interactions, which lead to faster excitation trapping. We give a pertubation theoretical explanation of this effect.
