An exact solution of the Peierls model with an arbitrary number of electrons in the unit cell
Brazovskii S.A. , Gordyunin S.A., Kirova N.N.
The electron spectrum and the static lattice deformations for an arbitrary number of electrons in a unit cell in the metallic phase are determined exactly in a self-consistent-field approximation for a one-dimensional Peierls system in the continuous model.
