Optical Bloch equations of light harvesting nanostructures — Alexander Carmele1, •Marten Richter1, Thomas Renger2, and Andreas Knorr1 — 1Institut für Theoretische Physik, AG Nichtlineare Optik und Quantenelektronik, Technische Universität Berlin, Hardenbergstr. 36, 10623 Berlin, Germany — 2Institut für Chemie und Biochemie, Freie Universität Berlin, Takustr. 3, 14195 Berlin, Germany
Within a Bloch equation approach [1], we calculate linear and pump-test spectra of Coulomb-coupled nanostructures (like pigments in pigment-protein complexes in LHC-II or the Fenna-Matthews-Olson (FMO) complex). The theory includes Förster-coupling induced excitation transfer between the nanostructures, electron-vibrational coupling between the nanosystems and their environment as well as the interaction with external optical fields and is based on many particle Liouville and cluster-expansion techniques. Hereby, we include self-consistently the structural data for the optical transition energies of pigments in protein environments and the spectral density of exciton-vibrational coupling [3].
