Quantum Dynamics of Photoactive Transition Metal Complexes. A Case Study of Model Reduction
Olga Bokareva, Oliver Kühn
Transition metal complexes for photochemical applications often feature a high density of electron-vibrational states characterized by nonadiabatic and spin-orbit couplings. Overal…
Formally Exact Simulations of Mesoscale Exciton Diffusion in a Photosynthetic Aggregate
Leonel Varvelo, Jacob K. Lynd, Brian Citty +2
The photosynthetic apparatus of plants and bacteria combine atomically precise pigment-protein complexes with dynamic membrane architectures to control energy transfer on the 10-10…
Interpreting fluorescence detected 2D electronic spectroscopy
Oliver Kühn, Tomas Mancal, Tõnu Pullerits
We explain current controversies regarding the interpretation of the cross peaks in the fluorescence detected coherent 2D spectroscopy.
Site-selective and real-time observation of bimolecular electron transfer during photocatalytic water splitting
Alexander Britz, Sergey I. Bokarev, Tadesse A. Assefa +13
Time-resolved X-ray absorption spectroscopy has been utilized to monitor the bimolecular electron transfer in a photocatalytic water splitting system for the first time. This has b…
The light-harvesting complex 2 of allochromatium vinosum: B800 absorption band splitting and exciton relaxation
Xiaomeng Liu, Oliver Kühn
Allochromatium (Alc.) vinosum has a double-peak structure of its absorption band around 800~nm. Previously, the excitonic origin of this feature has been demonstrated experimentall…
Unexpectedly large delocalization of the initial excitation in photosynthetic light harvesting
Khadga J. Karki, Junsheng Chen, Atsunori Sakurai +5
Electronic 2D spectroscopy allows nontrivial quantum effects in chemistry and biology to be explored in unprecedented detail. Here, we apply recently developed fluorescence detecte…
