Coherent Biexciton Transport in the Presence of Exciton-Exciton Annihilation in Molecular Aggregates
Rajesh Dutta, Chern Chuang
We present a theoretical framework for biexciton dynamics in molecular aggregates that explicitly treats populations and coherences across excitation manifolds within a reduced den…

Bath-induced stabilization of classical non-linear response in two dimensional infrared spectroscopy
Rajesh Dutta, Mike Reppert
Classical response functions have shown considerable promise in computational 2D IR modeling; however, a simple diagrammatic description, analogous to that for open quantum systems…

Energy Transfer Mechanism Under Incoherent Light Excitation in noisy Environments: Memory Effects in Efficiency Control
Rajesh Dutta, Biman Bagchi
Fluctuations in the energy gap and coupling constants in and between chromophores can play important role in the absorption and energy transfer across a collection of two level sys…
