15. The Hamiltonian used is (Formula presented)
16. The spin-orbit contribution (Formula presented) is not included in the Hamiltonian. (Formula presented) is the periodic electrostatic field from the ions and (Formula presented)
17. The left-hand side of Eq. (14) will contain the term (Formula presented). The Heisenberg field operators in the Green function now have a time dependence given by (Formula presented) where (Formula presented).
