Title: Coherence in photosynthesis?

Abstract: Coherent vibronic transport is a photophysical process that converts an electronic excitation on one pigment to an electronic and vibrational excitation on another pigment (or vice-versa) in a wave-like fashion. It has been suggested that biological pigment protein complexes garner a functional advantage for light harvesting via coherent vibronic transport mechanisms, but this remains controversial. In this talk I will summarize a model of vibronic transport that allows us to quickly diagnose the extent of vibronic coherence that should be expected in photosynthetic pigment protein complexes. These results suggest that vibronic transport is incoherent in photosynthetic light harvesting antenna.
