Self-consistent polaron states in the presence of simultaneous local and nonlocal exciton-phonon coupling
A canonical transformation method originally proposed by Munn and Silbey is used to diagonalize partially a model Hamiltonian which incorporates both local and nonlocal exciton phonon coupling. At the heart of the method ...
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 ...
