【Abstract】 Using the general form of the Hamiltonian of the electron phonon interaction, the specific expression of the quadratic term of the Hamiltonian describing an electron interacting with longitudinal optical phonons is given. 3D polaron in magnetic field by using the new Hamiltonian and the second order Rayleigh Schroding perturbation theory is studied, and the energy correction to the ground state and the first excited Landau level derived.更多还原
