Exact Solution of a Polaron Model in One Dimension

摘要

The Hamiltonian for a model of polaron, describing the interaction of electrons with optical phonons in one spatial dimension is diagonized in the scheme of quantum inverse scattering method. The spectrum of the collective excitations including strings of polarons is calculated. It is indicated that the formation of bipolaron is energetically unfavourable in our case. 10 refs.
