Formally exact fluorescence spectroscopy simulations for mesoscale molecular aggregates with scaling

Tarun Gera, Alexia Hartzell, Lipeng Chen +2

We present a size-invariant (i.e., ) scaling algorithm for simulating fluorescence spectroscopy in large molecular aggregates. We combine the dyadic adaptive hierarchy of pure…

MesoHops: Size-invariant scaling calculations of multi-excitation open quantum systems

Brian Citty, Jacob K. Lynd, Tarun Gera +2

The photoexcitation dynamics of molecular materials on the 10-100 nm length scale depend on complex interactions between the electronic and vibrational degrees of freedom, renderin…

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…
