14. Mention that the tunneling per se does not guarantee such a conversion: the coupling between the tunneling entities and other degrees of freedom, e.g., acoustic phonons, may lead to dissipation (see, e.g., Ref. 19).
15. It is quite probable that, due to the large masses of the ordering units usually involved in structural order-disorder transitions (not to mention decoherence), to convert these transitions into displacive ones factors such as quantum tunneling may be effective only at very low temperatures not available in experiments.
