Evidence for wavelike energy transfer through quantum coherence in photosynthetic systems
Article Abstract:
The two-dimensional Fourier transform electronic spectroscopy is employed to study the Fenna-Matthews-Olson (FMO) bacteriochlorophyll complex, which proves that the electronic quantum coherence play a very important role in the energy transfer processes within the system. The analysis reveals that the protein apart from helping in the rise of couplings also helps to modulate them with wavelike motions of charged residues to promote the coherence transfer.

Two-dimensional spectroscopy of electronic couplings in photosynthesis
Article Abstract:
Time-resolved optical spectroscopy is used to study vibrational and electronic dynamics by monitoring transient changes in excited state populations on a femtosecond timescale. Two-dimensional femtosecond infrared spectroscopy based on the heterodyne detection of three-pulse photon echoes has allowed the direct mapping of vibrational couplings, yielding transient structural information.

Quantum mechanics for plants
Article Abstract:
The extent to which photosynthetic organisms use quantum mechanics to maximize the capture and distribution of light is examined with the help of energy transfer at the submolecular scale. The studies show the way photosynthetic systems exploit energetic disorder to improve spectral coverage and reduce energy mismatches.
