Abstract

Harvesting sunlight to gain energy for life is initially done by light-harvesting antenna complexes containing chlorophyll and carotenoid molecules. Here we report on studies combining classical molecular-dynamics simulations with quantum-chemical calculations and a quantum-mechanical model to obtain a simplified model of the system. This model is then used to calculate optical properties. A similar approach can also be used to study charge transfer in DNA in water. Interestingly, the solvent molecules create large fluctuations in the base-pair energetics. The talk ends with some model-based studies on the influence of laser fields on the transport through molecular wires.
