The real and the imaginary parts of Δ1 (red solid) and Δ2 (blue dashed) in (a) and (b) are plotted as the function of the cavity decay rate κ. Here, we assume γe = 5γf and η = 4γf. The real and the imaginary parts of Δ1 (red solid) and Δ2 (blue dashed) in (c) and (d) are plotted as the function of the coupling strength η. Here, we assume γe = 5γf and κ = γf.
