Fig. 4: Polaritonic dissymmetry for the lowest-energy polariton, \({\tilde{g}}^{\alpha=1}\).

Shown are results as a function of (angular) cavity frequency Ω (a), transition dipole moment ratio μ2: μ1 (b), damping factor γ (c) and (angular) transition frequency difference ω2 − ω1 (d). Unless noted otherwise, A0 = 35 eV e−1c−1 and all other parameters are identical to Fig. 2, including an inter-dipole angle β21 = 45°, a crystal unit cell volume v = 4.5 nm3, and an effective high-frequency dielectric constant ϵ∞ = 8.0. The orange vertical line indicates points with the same parametrization across the different panels.
