Figure 2. The frequency ωr as a function of Δs (a) and Δo (b); the blue lines represent bound states, while the red lines represent the poles leading to exponential decay. The parameters that were unspecified before are: Δw=8ωm, Δs=4ωm, Δo=2ωm, ξw=3ωm, ξs=4ωm, ξo=2ωm, Eo=2 × 105ωm, κs=0.01ωm, κo=0.05ωm g=0.002ωm, and N=30.
