We compare the open system LGI violations with that corresponding to close system case.
We plot the real part of K4 for the closed system and that in presence of the reservoir at zero temperature. We consider three different values of s (s = 0.5, s = 1, s = 3) corresponding to sub-Ohmic, Ohmic and super-Ohmic environments with cutoff frequency Λ = ω0/3. We consider four different values of the coupling strengths γ = 0.05, 0.2, 0.5, 1.0.
