Quantum transport in quantum networks and photosynthetic complexes at
the steady state    [PDF]

Daniel Manzano

Recently, several works have analyzed the efficiency of photosynthetic complexes in a transient scenario and how such an efficiency is affected by environmental noise. Here, following a quantum master equation approach, we study the energy and excitation transport in fully connected networks both in general and in the particular case of the FMO complex. The analysis is carried out for the steady state of the system where excitation energy is constantly "flowing" through the system. Steady state transport scenarios are particularly relevant if the evolution of the quantum system is not conditioned on the arrival of individual excitations. By adding dephasing to the system, we analyze the possibility of noise-enhancement of the quantum transport.
