The Fröhlich Charge-Density-Wave as a Lattice of Davydov’s Solitons

摘要: A self-consistent state of the conduction electrons and lattice deformation in one-dimensional metal was considered by Frohlich 19541. This then called charge density wave (CDW) today it is widely studied both theoretically experimentally2-4. The assumption that only one phonon mode with number q = 2k F (k Fermi number) occupied macroscopically interacts intensively electrons, often used for explanation certain properties CDW.
