Simulating optical linear absorption for mesoscale molecular aggregates: an adaptive hierarchy of pure states approach
Tarun Gera, Lipeng Chen, Alex Eisfeld +3
In this paper, we present a new method for calculating linear absorption spectra for large molecular aggregates, called dyadic adaptive HOPS (DadHOPS). This method combines the ada…

Exact Results for the Tavis-Cummings and Hckel Hamiltonians with Diagonal Disorder
Tarun Gera, K. L. Sebastian
We present an exact method to calculate the electronic states of one electron Hamiltonians with diagonal disorder. We show that the disorder averaged one particle Green's function…

Effects of disorder on polaritonic and dark states in a cavity using the disordered Tavis-Cummings model
Tarun Gera, K. L. Sebastian
We consider molecules confined to a microcavity whose dimensions are such that an excitation of the molecule is nearly resonant with a cavity mode. We investigate the situation whe…
