  In this paper, starting from a quantum master equation, we discuss the
interaction between two negatively charged Nitrogen-vacancy color centers in
diamond via exciton-polaritons propagating in a two-dimensional transition
metal dichalcogenide layer in close proximity to a diamond crystal. We focus on
the optical 1.945 eV transition and model the Nitrogen-vacancy color centers as
two-level (artificial) atoms. We find that the interaction parameters and the
energy levels renormalization constants are extremely sensitive to the distance
of the Nitrogen-vacancy centers to the transition metal dichalcogenide layer.
Analytical expressions are obtained for the spectrum of the exciton-polaritons
and for the damping constants entering the Lindblad equation. The conditions
for occurrence of exciton mediated superradiance are discussed.
