Multi-exciton ultrafast energy transfer processes in molecular systems with quantum environment
Annotation in Czech
Future quantum technologies demand exploring systems with ever-increasing complexity and number of degrees of freedom (DOF). Natural photosynthetic machinery offers an extremely valuable model of open quantum systems (OQS) with well-defined spatial structures, well-characterized dynamics, and a variable number of quantum DOF. Most of the photosynthetic function is performed in the well-understood single exciton regime. However, a portion of natural light energy harvesting occurs in a less understood regime of higher excited states and multiple excitons. We will use photosynthesis as a model to study multi-exciton and cooperative effects by recently developed multi-exciton- and coherent action-detected time-resolve spectroscopies. We will develop a novel scalable wavefunction description of OQS to keep track of both the excitonic and environmental evolutions and their entanglement. We will quantify the cooperative quantum effects in the photosynthetic process and develop novel synergy of theoretical and experimental methods to explore the controlled evolution of large quantum systems.
