The decay of δ D(t) and δ Z(t) in the in-frequency-weighted case with different K (K < Kc). The solid lines are the direct numerical solutions of Eq. (3) (here Ki = 1 and Gj = K ωj) and the dashed lines are the fitted curves with exponent as Eqs. (36) and (37). The natural frequency obeys g(ω)=γπ[(ωΔ)2+γ2] . (a) and (b) K = 1.6, Δ = 0.5, γ = 0.5. (c) and (d) K = 1.4, Δ = 0.5, γ = 0.5. In the numerical simulations, we set the total number of oscillators to N = 100000, and the initial phases for all oscillators are identical.
