Unravelling coherences in the FMO complex
Erling Thyrhaug, Roel Tempelaar, Marcelo Alcocer +5
The idea that excitonic state (electronic) coherences are of fundamental importance to natural photosynthesis gained popularity when, a decade ago, slowly dephasing quantum beats w…
Exciton-Exciton Annihilation Is Coherently Suppressed in H-Aggregates, but Not in J-Aggregates
Roel Tempelaar, Thomas L. C. Jansen, Jasper Knoester
We theoretically demonstrate a strong dependence of the annihilation rate between (singlet) excitons on the sign of dipole-dipole couplings between molecules. For molecular H-aggre…
Vibronic exciton theory of singlet fission. II. Two-dimensional spectroscopic detection of the correlated triplet pair state
Roel Tempelaar, David R. Reichman
Singlet fission, the molecular process through which photons are effectively converted into pairs of lower energy triplet excitons, holds promise as a means of boosting photovoltai…
Vibronic exciton theory of singlet fission. I. Linear absorption and the anatomy of the correlated triplet pair state
Roel Tempelaar, David R. Reichman
Recent time-resolved spectroscopic experiments have indicated that vibronic coupling plays a vital role in facilitating the process of singlet fission. In this work, which forms th…
