摘要: We present a scattering theory for the efficient transmission of an excitation across finite network with designed disorder. show that presence randomly positioned networks sites allows to significantly accelerate transfer processes as compared dimer structure, if only disordered Hamiltonians are constrained be centrosymmetric, and exhibit dominant doublet in their spectrum. identify cause this efficiency enhancement constructive interplay between disorder-induced fluctuations doublet's splitting coupling strength input output channels. find characteristic these together channel fully control efficiency.
