WebWe represent the Hamiltonian in the basis of free neutral atoms. In the Wannier representation, the system Hamiltonian is [ 31 ] (1) where the zeroth-order Hamiltonian (2) consists of the single-particle Hamiltonian of the electrons in the field of the ionic cores (3) and the harmonic phonon Hamiltonian for the motion of the ion cores (4) http://electron6.phys.utk.edu/qm1/modules/m9/magfield.htm
