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) WebAug 3, 2016 · The SOC Hamiltonian used here is the phenomenological as we wish to correlate the SOC in magnetic complexes and in atoms. For symmetry based selection rules, the matrix elements to evaluate are . The application of the Wigner–Eckart theorem on the spin part of the Hamiltonian leads to the expression [ 49 ]: (5)
