Titulo: Optimal design for quantum transport across a disordered system
Resumen:
Lossless and rapid transport of elementary excitations in complex materials is a crucial prerequisite for functional optimisation, from information transfer to energy conversion. With increasing complexity of the underlying structures, random perturbationsbecome unavoidable, and rather be incorporated than fought when seeking robust optimisation strategies. Inspired by the recent debate on light harvesting units, we propose a general mechanism for highly efficient quantum transport through finite, disordered 3D networks, which relies on an appreciable statistical weight of rare events, is robust against reconformations, can be controlled by tuning coarse-grained quantities, and thus qualifies as a general design principle. Statistical sampling in the vicinity of FMO light harvesting structure data suggests that such design principles, potentially useful for novel artificial devices, may already be implemented in Nature.
