So far, we only consider an indirect coupling of the molecules to each other. Now, we also include a direct intermolecular dipolar coupling term. Fig. shows the rate k as a function of the intermolecular dipolar coupling ∆ for a homodimer outside (black lines) and inside (colored lines) the cavity with three different photon frequencies. The results for the parallel dipole configuration are displayed as the solid lines and those for the anti-parallel configuration as the dotted lines.
