Ultrafast charge transfer plays a key role in chemical reactions, biological processes, and technical applications. For example, charge transfer after photoexcitation on the femtosecond time scale and the associated long-lived coherences observed in photosynthetic systems or photovoltaic blends have been invoked to explain the high efficiencies of energy conversion in these systems.
