WebNov 29, 2024 · Our prof showed us a derivation where he approximated the dirac equation to the non-relativistic case and said that the extra terms besides the schroedinger equation are correction terms and that one of them is the so called spin-orbit coupling. $E_ {SL}=-\frac {e} {2m_e^2c^2r}\frac {1} {r}\frac {dV} {dr}\vec {S}\cdot \vec {L}$. WebSpin-orbit coupling can be derived by reduction of the Dirac equation to non-relativistic limit, as one of several relativistic corrections. It is then generally expressed as H s o ∝ [ p × ∇ U ( r)] ⋅ S where S = ℏ σ / 2. ( See this answer and references therein.)
Why spin-orbit coupling (term) is relativistic? ResearchGate
In quantum physics, the spin–orbit interaction (also called spin–orbit effect or spin–orbit coupling) is a relativistic interaction of a particle's spin with its motion inside a potential. A key example of this phenomenon is the spin–orbit interaction leading to shifts in an electron's atomic energy levels, due to … See more This section presents a relatively simple and quantitative description of the spin–orbit interaction for an electron bound to a hydrogen-like atom, up to first order in perturbation theory, using some semiclassical See more • Condon, Edward U. & Shortley, G.

WebMay 27, 2024 · When spin-orbit coupling is taken into account, each n, ℓ state gives rise to two levels with total angular momentum j = ℓ ± 1 2 Show that the total number of states with the same values of n and ℓ is unchanged. This illustrates the general point that recoupling the angular momenta never changes the total number of states available.
