We suggest a method of studying coherence in finite-level systems coupled to the environment and use it for the Hamiltonian that has been used to describe the light-harvesting pigment-protein complex. The method works with the adiabatic states and transforms the Hamiltonian to a form in which the terms responsible for decoherence and population relaxation are separated out. Decoherence is then accounted for nonperturbatively and population relaxation using a Markovian master equation. Almost… 
Adiabatic eigenfunction based approach to coherent transfer: application to the Fenna-Matthews-Olson (FMO) complex and the role of correlations in the efficiency of energy transfer.
These calculations suggest that the presence of anticorrelations, in contrast to correlations, make the excitation transfer more facile, and a Markovian type of master equation could be used for evaluating the population relaxation.
An Almost Analytical Approach to Simulating 2D Electronic Spectra

Two-Dimensional Electronic-Vibrational Spectroscopy of Coupled Molecular Complexes: A Near-Analytical Approach.
Although the interpretation of 2DEV spectra is considerably more complex than that for weakly coupled systems, the richness of the spectra and the necessity to consider both visible and infrared transition moments suggest that such analysis will be very valuable in characterizing the role of vibronic effects in ultrafast molecular dynamics.

While resonance is desirable, a moderate electronic coupling has a stronger positive effect in contrast to a large electronic coupling which results in delocalised excitations across molecules and hampers unidirectional transport.

A critical assessment of published and recently measured optical spectra is provided and it is demonstrated that the value of Eλ is most likely about 15–22 cm−1 and suggested that spectra reported in the literature exhibit varied peak positions due to different purification/isolation procedures or destabilization effects.
