Fig. 3: Polaritonic dissymmetry \({\tilde{g}}^{\alpha }\) as a function of (angular) cavity frequency Ω for the minimal configuration of two transition dipoles.

Shown are results for a vector potential A₀ = 35 eV e⁻¹c⁻¹ (a, b) and for A₀ = 70 eV e⁻¹c⁻¹ (c, d). Depictions of \({\tilde{g}}^{\alpha }\) are separated over two Panels to avoid overlap, and in each Panel corresponds to the polariton dispersions indicated by the solid curves (other polariton dispersions are indicated by the dashed curves as a reference). Results are obtained by numerical diagonalization of the Hamiltonian given by Eq. (13), with inter-dipole angle β₂₁ = 45°, (angular) transition frequencies ω₁ = 2.0 eV ℏ⁻¹ and ω₂ = 3.0 eV ℏ⁻¹, transition dipole moments μ₁ = μ₂ = 10.0 D, crystal unit cell volume v = 4.5 nm³, and high-frequency dielectric constant ϵ_∞ = 8.0.
