The cooling possibility P as a function of coupling strength J (in units of ω_m) when the optomechanical coupling rates are equal to G₁/ω_m = G₂/ω_m = 0.2 (blue scatter plot) or different G₁/ω_m = 0.2, G₂/ω_m = 0.1 (red scatter plot). The dimensionless time is cut off to ω_m t = 100, and the other parameters are the same as those in Fig. 3.
