Polarons, localization, and excitonic coherence in superradiance of biological antenna complexes
A real-space formulation of time-resolved fluorescence of molecular aggregates is developed using the one-exciton density matrix ρ(t) of the optically driven system. A direct relationship is established between the ...
Superradiance coherence sizes in single-molecule spectroscopy of LH2 antenna complexes
The distribution of cooperative radiative decay rates in photosynthetic aggregates is calculated using a Frenkel exciton model with static diagonal disorder. This distribution which depends on both the exciton coherence ...
Spin versus boson baths in nonlinear spectroscopy
The third-order optical response function of a chromophore coupled to a bath consisting of noninteracting two-level systems (TLSs) undergoing stochastic jumps is calculated. The results can be applied to a broad class of ...
