Diffusion in the presence of correlated dynamical disorder and coherent exciton transfer in the non-Markovian limit
Rajesh Dutta, Biman Bagchi
The presence of static off-diagonal disorder promotes coherent exciton transport while diffusive motion can be recovered in the presence of fluctuations in the diagonal and off-dia…

Signatures of quantum coherence in the optical line shape of an exciton in the presence of dynamic disorder
Rajesh Dutta, Kaushik Bagchi, Biman Bagchi
We address the effects of quantum coherences on the optical line shape of an exciton in the presence of dynamic disorder. We consider a one-dimensional excitonic system that consis…

Exciton transfer dynamics and quantum diffusion in a lattice of two level systems: Interplay between transport and coherent population transfer dynamics
Rajesh Dutta, Biman Bagchi
We study excitation transfer dynamics in a lattice of two level systems characterized by dynamic disorder. The diagonal and off-diagonal energy disorders arise from the coupling of…
