Ls coupling hamiltonian

Similar to the electron spin resonance (ESR) in which electrons can be excited with an electromagnetic wave with the energy given by the Zeeman effect , in EDSR the resonance can be achieved if the frequency is related to the energy band split given by the spin–orbit coupling in solids. LS coupling is a change of base that you have to perform in order to diagonalize your Hamiltonian H when angular momentum L and spin S are no longer conserved (do not commute with H). Spin-orbit is a relativistic effect that couples motion, potential and spin of particle, it is a specific term in the Hamiltonian. In a magnetic field, the six split like this. Now, let's look at transitions to the l = 0 derived states. The selection rules with Landau Spin Orbit Coupling are analogous to the orbital selection rules. Changes in quantum number j, are plus or minus 1, and changes in the total magnetic quantum number, m sub j are 0 and plus 1 or minus 1. The Spin Hamiltonian Revisited •Life is easier if: Examples: 2) interaction with dipole field of other nuclei 3) spin-spin coupling •In general, is the sum of different terms representing different physical interactions.

For light atomic systems with small value of nuclear charge, the electrostatic hamiltonian term is much stronger than the spin orbit coupling that increases with increasing Z, therefore in this case we use LS coupling.

Such interactions can be derived in a classical way. approximation is called LS coupling or Russell-Saunders coupling. The things which are coupled in this coupling are: 1. All the individual orbital angular momenta couple together to make ^L. 2. All the individual spin angular momenta couple together to make ^S. Because of this coupling, the one electron wavefunctions .
