Optimally designed quantum transport across disordered networks
arXiv:1207.4072 · doi:10.1103/PhysRevLett.111.180601
Abstract
We establish a general mechanism for highly efficient quantum transport through finite, disordered 3D networks. It relies on the interplay of disorder with centro-symmetry and a dominant doublet spectral structure, and can be controlled by proper tuning of only coarse-grained quantities. Photosynthetic light harvesting complexes are discussed as potential biological incarnations of this design principle.
