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 sizes and the aggregate geometry can be directly observed using single-molecule...

Description
Summary: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 sizes and the aggregate geometry can be directly observed using single-molecule spectroscopy. Comparison is made with a dynamic exciton self-trapping (polaron) mechanism for localization.
