Dependence of PAT location on modulation frequency ω and coupling strength Ω1.
(a,b) The minimum value of population distribution P1, Min(P1), as a function of the modulation frequency ω with Ω2 = 2 and Ω2 = 3 respectively. Other parameters are chosen as Ω1 = 1 and A = 6.6. (c) Min(P1) versus Ω2 with different values of Ω1. Other parameters are chosen as ω = 3 and A = 6.6.
