However, some recent papers based on molecular dynamics simulations cast doubt on the main claims of that paper.
The conclusion of the paper, Quest for Spatially Correlated Fluctuations in the FMO Light-Harvesting Complex by Carsten Olbrich, Johan Strumpfer, Klaus Schulten, and Ulrich Kleinekathofer
The comparison between present results and the reported experimental findings is difficult. It seems to be clear, though, that site correlations do not play a role at physiological conditions and that the biological function of the FMO complex is not affected by spatial site energy correlations. A similar conclusion has already been drawn for the light-harvesting II complex of Rhodospirillum molischianum in a similar study.
