Effect of Thermal Oscillations of Molecules on the Properties of Solitons in One-Dimensional Molecular Lattices

摘要

A quantum mechanical treatment of the collective excitations in one-dimensional molecular chains is presented and the influence of thermal oscillations on the properties of solitary excitations is taken into account. The general case of exciton-phonon interaction is considered and the soliton state is found as a solution of a nonlinear Schroedinger equation with nonlinearities of third and fifth order.
