Effect of External Factors on Physical and Chemical Transformations Polaron in an Electric Field as a Generator of Coherent Lattice Vibrations

Resumo

The dynamics of polaron on a one-dimensional harmonic lattice in a constant electric field is considered in detail. Calculations were performed with parameters approximately corresponding to the parameters of polyacetylene and DNA. The polaron in a constant field comes out to a steady state characterized by a constant profile and velocity. The energy imparted to the polaron by the electric field is converted to longitudinal coherent lattice vibrations. For several thousand lattice points, these vibrations are constant in their frequency and wavenumbers, which weakly depend on the strength of electric field.
