Abstract Kramer: Energy transfer in photosynthetic complexes: disorder, noise and coherence

I discuss the modeling of energy flow in photosynthetic apparatus, with an emphasis on the comparison of theoretical predictions for time and frequency resolved spectroscopy with experimental data. Using an efficiently accelerated implementation of the hierarchical equations of motion (HEOM) method allows one to discuss different light harvesting systems with different couplings of electronic and vibrational degrees of freedom [2] and to elucidate the excitation pathways.
