(a) The initial population in the metastable state is ρ bb (0) = 0.8. The attached state is ρ aa (0) = 0.2. The decay rate of metastable state is γ b = 7. The decay rate of the attached state is γ a = 4. The frequency difference of the two excited states is ω ba = 4. This curve corresponds to a stretch activation. (b) No population initially existed in the excited state ρ aa (0) = 0. ρ bb (0) = 0.5, γ b = 7, γ a = 7, ω ba = 4. This corresponds to a release-activation.
