Electronic excitations in the Peierls-Frohlich state
Brazovskii S.A.
It is shown that the stationary electronic excitations in the Peierls state are tight-binding polarons with energy in the interior of the forbidden band, with large mass, and with anomalous charge. Within the framework of the Frohlich model, the charge of any autolocalized state is equal to zero. An exact solution of the soliton type is obtained, with energy at the center of the forbidden band, with zero charge, and with spin 1/2.
