The relationship between the exponent R(t) (non-dissipative case, κ = 0) and Rd(t) (dissipative case, κ = 0.02) and the time t is plotted in (a) and (b), respectively. The parameters are λ = 1, G1 = G2, Δ1 = 2G2, and θ = π/2. The red-solid line, blue-dashed line and black-dash-dotted line denote the case of G2 = 1, 1.5 and 2, respectively.
