Pseudomode Approach and Vibronic Non-Markovian Phenomena in Light-Harvesting Complexes

Abstract

The pseudomode approach is discussed, with emphasis on the Gorini-Kossakowski-Sudarshan-Lindblad form of this approach. The connection of the pseudomode approach with solutions of the Friedrichs model and the Jaynes-Cummings model with dissipation at zero temperature is shown. The obtained results are applied to the description of non-Markovian phenomena in the Fenna-Matthews-Olson complexes. Estimations based on experimental data are presented. A generalization of the pseudomode approach to the finite-temperature case with the use of the deformation technique is discussed.
