Characterizing the functional role of quantum coherence in energy transfer
Hallmann Ãskar Gestsson, Alexandra Olaya-Castro
Quantum coherence is understood to play a role in excitation energy transfer in open quantum systems, yet a quantitative approach to assessing its influence on the transfer process…
Signatures of coherent energy transfer and exciton delocalization in time-resolved optical cross correlations
Hallmann Ãskar Gestsson, Alexandra Olaya-Castro
We investigate how optical second-order cross correlations witness the quantum features of a prototype donor-acceptor light-harvesting unit. By considering a pair of detuned two-le…
Perturbation-theory approach for predicting vibronic selectivity by entangled-photon-pair absorption
C. D. Rodriguez-Camargo, H. O. Gestsson, C. Nation +2
Using second-order perturbation theory in the light-matter interaction, we derive an analytical approximation for the vibronic populations of a diatomic system excited by ultrabroa…
Non-perturbative exciton transfer rate analysis of the Fenna-Matthews-Olson photosynthetic complex under reduced and oxidised conditions
Hallmann Ã. Gestsson, Charlie Nation, Jacob S. Higgins +2
Two-dimensional optical spectroscopy experiments have shown that exciton transfer pathways in the Fenna-Matthews-Olson (FMO) photosynthetic complex differ drastically under reduced…
