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

Autor: Citty, Brian, Lynd, Jacob K., Gera, Tarun, Varvelo, Leonel, Raccah, Doran I. G. B.

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, rendering exact calculations difficult or intractable. The adaptive Hierarchy

Simulating optical linear absorption for mesoscale molecular aggregates: an adaptive hierarchy of pure states approach

Autor: Gera, Tarun, Chen, Lipeng, Eisfeld, Alex, Reimers, Jeffrey R., Taffet, Elliot J., Raccah, Doran I. G. B.

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 adaptive HOPS (adHOPS) framework, which uses locality to improve computat

Exact Results for the Tavis-Cummings and H$\boldsymbol{\ddot{u}}$ckel Hamiltonians with Diagonal Disorder

Autor: Gera, Tarun, Sebastian, K. L.

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 can be calculated directly, using a deterministic complex (non-Hermiti

Effects of disorder on polaritonic and dark states in a cavity using the disordered Tavis-Cummings model

Autor: Gera, Tarun, Sebastian, K. L.

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 where the excitation energies of the molecules are randomly distributed w
