- Abstract summary: We investigate the effects of system-environment, inter-environment couplings and coherence of the structured environment on the steady state heat flux.
Our calculations reveal that there exists a non-monotonic and non-trivial relationship between the steady-state heat flux and the mentioned parameters.

- Abstract: The high energy transfer efficiency of photosynthetic complexes has been a
topic of research across many disciplines. Several attempts have been made in
order to explain this energy transfer enhancement in terms of quantum
mechanical resources such as energetic and vibration coherence and constructive
effects of environmental noise. The developments in this line of research have
inspired various biomimetic works aiming to use the underlying mechanisms in
biological light harvesting complexes for improvement of synthetic systems. In
this article we explore the effect of an auxiliary hierarchically structured
environment interacting with a system on the steady-state heat transport across
the system. The cold and hot baths are modeled by a series of identically
prepared qubits in their respective thermal states, and we use collision model
to simulate the open quantum dynamics of the system. We investigate the effects
of system-environment, inter-environment couplings and coherence of the
structured environment on the steady state heat flux and find that such a
coupling enhances the energy transfer. Our calculations reveal that there
exists a non-monotonic and non-trivial relationship between the steady-state
heat flux and the mentioned parameters.
