Figure 3. (a) Coherent coupling strength Ω22/γ0. (b) Cross-damping rate Γ22/γ0. This graph is drawn as a function of the dimensionless parameter $x={k}_{0}r$ with two electric dipoles parallel to the x-axis. The relative displacement vector ${\boldsymbol{r}}$ is along the $\hat{z}$ direction. The parameter S is chosen to be S = 0.1.
