A Witness for Coherent Electronic vs Vibronic-Only Oscillations in Ultrafast Spectroscopy
(American Institute of Physics, 2012)
We report a conceptually straightforward witness that distinguishes coherent electronic oscillations from their vibronic-only counterparts in nonlinear optical spectra of molecular aggregates. Coherent oscillations as a ...
Exciton Transport in Thin-Film Cyanine Dye J-Aggregates
(American Institute of Physics, 2012)
We present a theoretical model for the study of exciton dynamics in J-aggregated monolayers of fluorescent dyes. The excitonic evolution is described by a Monte-Carlo wave function approach which allows for a unified ...
Multipartite Quantum Entanglement Evolution in Photosynthetic Complexes
(American Institute of Physics, 2012)
We investigate the evolution of entanglement in the Fenna-Matthew-Olson (FMO) complex based on simulations using the scaled hierarchy equation of motion (HEOM) approach. We examine the role of multipartite entanglement in ...
Exciton Coherence Lifetimes from Electronic Structure
(American Institute of Physics, 2012-04-06)
We model the coherent energy transfer of an electronic excitation within covalently linked aromatic homodimers from first-principles. Our results shed light on whether commonly used models of the bath calculated via detailed ...
Engineering Directed Excitonic Energy Transfer
(American Institute of Physics, 2010)
We provide an intuitive platform for engineering exciton transfer dynamics. We show that careful consideration of the spectral density, which describes the system-bath interaction, leads to opportunities to engineer exciton ...
Environment-Assisted Quantum Walks in Photosynthetic Energy Transfer
(American Institute of Physics, 2008)
Energy transfer within photosynthetic systems can display quantum effects such as delocalized excitonic transport. Recently, direct evidence of long-lived coherence has been experimentally demonstrated for the dynamics of ...
Absence of Quantum Oscillations and Dependence on Site Energies in Electronic Excitation Transfer in the Fenna–Matthews–Olson Trimer
(American Chemical Society, 2011)
Energy transfer in the photosynthetic Fenna–Matthews–Olson (FMO) complex of green sulfur bacteria is studied numerically taking all three subunits (monomers) of the FMO trimer and the recently found eighth bacteriochlorophyll ...
