Abstract

We calculate microscopic parameters in the Davydov model on the basis of the bisoliton idea. We also prove that the displacement β(η) in Davydov theory satisfies the φ4 field form. Critical temperature is studied from two aspects: the statistics of lattice kinks and the exciton model considering thermal vibrations. The agreement between theoretical and experimental data for the critical temperature of organic superconductors supports Davydov’s bisoliton theory.
