DNA nanotechnology has now enabled the self-assembly of almost any prescribed 3-
dimensional nanoscale structure in large numbers and with high fidelity. These structures …

The influence of exciton–vibrational coupling on the optical and transport properties of
molecular aggregates is an old problem that gained renewed interest in recent years. On the …

Photosynthetically active membranes of certain bacteria and higher plants contain antenna
systems which surround the reaction center to increase its absorption cross section for the …

Advancing the debate on quantum effects in light-initiated reactions in biology requires clear
identification of non-classical features that these processes can exhibit and utilize. Here we …

Organic molecules store the energy of absorbed light in the form of charge-neutral molecular
excitations–Frenkel excitons. Usually, in amorphous organic materials, excitons are viewed …

Exciton delocalization plays a prominent role in the photophysics of molecular aggregates,
ultimately governing their particular function or application. Deoxyribonucleic acid (DNA) is a …

Control over the strength of excitonic coupling in molecular dye aggregates is a substantial
factor for the development of technologies such as light harvesting, optoelectronics, and …

We computed the optical properties of a large set of molecular crystals (∼ 2200 structures)
composed of molecules whose lowest excited states are strongly coupled and generate …

Molecular excitons, which propagate spatially via electronic energy transfer, are central to
numerous applications including light harvesting, organic optoelectronics, and nanoscale …

Coherent exciton delocalization in dye aggregate systems gives rise to a variety of intriguing
optical phenomena, including J-and H-aggregate behavior and Davydov splitting. Systems …
