Dephasing assisted transport on a biomimetic ring structure

We address two-level systems (TLSs) arranged in ring configurations affected by static disorder. In particular, we investigate the role of dephasing in the transport of an excitation along the ring. We compare the efficiency of the transfer process on isotropic rings and on biomimetic rings modeled according to the structure of light-harvesting (LH) complexes. Our analysis provides a simple but clear and interesting example of how an interplay between the coherent dynamics of the system and the incoherent action of the environment can enhance the transfer capabilities of disordered lattices.
