An observation, similar to the one made in a previous study , that is evident from Fig. is that the classical ⟨P iso ⟩ seems to track the quantum one rather well for certain initial states. In particular, from Fig. (a) and (c) the classical-quantum correspondence can be clearly seen for the initial state with q i = -0.9, whereas Fig. shows that the correspondence is poor for the initial state with q i = -0.439. However, Fig. (a) indicates that the regimes of enhancement and suppression of the quantum and classical scaled ⟨P iso ⟩ are qualitatively similar. Moreover, Fig. shows that the classical ω min c exhibits a qualitatively similar trend as in the quantum case. Note that for the model of interest, the presence of tunneling is expected to make the correspondence weaker. In fact, previous study associated the suppression in ⟨P iso ⟩ with two quantum effects -a stiffening of the TS valley resulting in lesser number of accessible TS states and the broadening of the barrier with increasing η leading to reduced tunneling. Ironically, the latter effect should make the correspondence better while the former effect should manifest as a decreased classical flux across the TS. Although the interplay of quantum and classical effects are expected to be subtle in the different regimes, Fig. does motivate us to look more carefully at the classical phase space.
