Query: Enhancement of quantum transport efficiency in a noisy spin channel   In this paper, based on the notion of pseudomode framework introduced by
Garraway in [Phys. Rev. A 55, 2290 (1997)], we propose a mechanism for
enhancing the efficiency of excitation energy transport in a spin channel which
is in contact with a Lorentzian reservoir, through the inclusion of other
similar auxiliary spin chains into the reservoir. To this aim, a Lindblad-type
master equation for the dynamics of the transport process is provided on the
basis of pseudomode approach. It is figured out that increasing the number of
auxiliary chains in the reservoir enhances the efficiency of transport or
equivalently, rises the population of the reaction center attached to the end
of the channel. Moreover, it is interesting to note that the mechanism has
better efficiency for the channels with longer lengths.
