Exciton transfer efficiency and exciton-phonon information flow in
photosynthetic complexes
Long-lived electronic coherences in various photosynthetic complexes at
cryogenic and room temperature have generated vigorous efforts in both
theory and experiment to understand their origins and explore their
potential role to efficient excitonic energy transport. This talk
introduces the fundamental concept of environment-assisted quantum
transport (ENAQT) and presents recent experimental evidence for its
relevance. Furthermore, ENAQT is confirmed numerically in the
state-of-the-art hierarchy equation of motion approach. Finally, recent
developments in measures for non-Markovianity are utilized to study the
intricate excitonic-vibrational dynamics in terms of the information
flow between electronic and nuclear degrees of freedom.
