Non-Equilibrium Quantum Dynamics in Soft Organi and Biological Matter
We investigate the non-equilibrium quantum transport of electronic excitations across open soft-condensed matter systems. Notable applications concern for example, the study of exciton energy transfer in photosynthetic protein-chromophore complexes. We have recently developed a rigorous bottom-up approach to these processes based on the effective quantum field theory formalism, in which the time evolution of the electronic excitations is obtained from appropriate Feynman diagrams without the need to perform computational simulations of the conformational vibrations. On-going applications concern the study of charge transfer processes in biopolymers and organic transistors, and of exciton transfer in specific photosynthetic complexes and in biomimetic conjugate polymers.
