Signatures of coherent energy transfer and exciton delocalization in time-resolved optical cross correlations
Hallmann Óskar 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…
Non-perturbative exciton transfer rate analysis of the Fenna-Matthews-Olson photosynthetic complex under reduced and oxidised conditions
Hallmann Ó. 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…
Theoretical study of the influence of the photosynthetic membrane on B800-B850 energy transfer within the peripheral light-harvesting complex LH2
Chawntell Kulkarni, Hallmann Óskar Gestsson, Lorenzo Cupellini +2
Photosynthetic organisms rely on a network of light-harvesting protein-pigment complexes to efficiently absorb sunlight and transfer excitation energy to reaction center proteins f…
Photon correlation time-asymmetry and dynamical coherence in multichromophoric systems
Charlie Nation, Hallmann Oskar Gestsson, Alexandra Olaya-Castro
We theoretically investigate polarization-filtered two-photon correlations for the light emitted by a multichromophoric system undergoing excitation transport under realistic excit…
Two-colour photon correlations probe coherent vibronic contributions to electronic excitation transport under incoherent illumination
Charlie Nation, Valentina Notararigo, Hallmann Oskar Gestsson +2
Identifying signatures of quantum coherent behaviour in photoactive systems that are maintained in stationary states away from thermal equilibrium is an open problem of wide intere…
Coherence specific signal detection via chiral pump-probe spectroscopy
David I. H. Holdaway, Elisabetta Collini, Alexandra Olaya-Castro
We examine transient circular dichroism spectroscopy (TRCD) as a technique to investigate signatures of exciton coherence dynamics under the influence of structured vibrational env…
