Green's function calculations for two-dimensional arrays of molecular emitters — •Davide Torriglia, Daniel M. Reich, and Christiane P. Koch — Freie Universität Berlin, Arnimallee 14, D-14195 Berlin, Germany

Collective excitations of atomic or molecular arrays have recently attracted a lot of interest in quantum optics as a tool to control the propagation, scattering and storage of light fields.

In this project, we aim to describe the coupling of a two-dimensional molecular array with a quantized light mode and investigate the effect of a graphene substrate on the collective state of the molecules.

As a first step towards this, we calculate the dyadic Green's function for various geometries to describe the propagation of the electromagnetic field classically according to Maxwell's equations.

Employing the resulting Green's functions in quantum mechanical simulations, we aim to directly account for the field-propagation effects on molecular arrays in complex geometries, such as those used in the generation of polaritons in modern experiments.
