Soliton excitations in the model of a large-radius polaron

V. K. Fedyanin, V. Yu. Yushankhai


Abstract: The interaction between an electron and longitudinal optical pho'nons in a one-dimensional polar crystal is investigated. A nonlinear Schrödinger equation having a soliton solution is obtained for the electron wave function.
