Variation of the decay rate for a given macroscopic quantum system, (a) plot of Γ(τ) as a function of τ and \(\tilde{h}\) with Δ = 1, η = 0.001, ωc = 10 for an Ohmic environment (s = 1), (b) Same as (a) but now we have a sub-Ohmic environment with s = 0.8, (c) Same as (a) but now we have a super-Ohmic situation with s = 2.
