The optimization topography of exciton transport

By Torsten Scholak, Thomas Wellens and Andreas Buchleitner

Abstract

Stunningly large exciton transfer rates in the light harvesting complex of photosynthesis, together with recent experimental 2D spectroscopic data, have spurred a vivid debate on the possible quantum origin of such efficiency. Here we show that configurations of a random molecular network that optimize constructive quantum interference from input to output site yield systematically shorter transfer times than classical transport induced by ambient dephasing noise.Comment: 5 pages, 1 figur
