Solitons, Electrets, and Frohlich Waves

Let us now consider the one-dimensional dynamics occurring on the macromolecular chains. Davydov has shown that a vibrational soliton—namely, a localized excitation strictly bound to a localized deformation—occurs on one-dimensional chains made by weakly bound monomers under two conditions  

Under the above conditions solitons are created and travel quite slowly on the chain exhibiting a remarkable stability when their lifetime is compared with the one of the original excitation. Solitons have been therefore proposed as the long-range carriers of the energy produced by metabolic reactions and stored on the molecules. For this reason they were used in a model of muscle contraction by Davydov. 

The above-discussed mechanisms are particular ones. It is possible to integrate them in a provisional, unified scheme giving a partial qualitative
