Figure 7. (a) Jopt versus κc, at the optimal ropt. (b) Vmin versus κc, after optimizing both r and J. Both blue (nth = 0) and red lines (nth = 5) are obtained from miniming equation (27). The dots denote the approximate results of equations (32) and (33). Other parameters: δ = 0.01ωm, G2 = 0.1ωm, γ1 = γ2 = 10−5ωm, Δ1 = −Δ2 = 2ωm, κ1 = κ2 = κ = 0.2ωm.
