SUMMARY

The LS coupling scheme, or spin-orbit coupling, is a fundamental concept in atomic physics that describes the interaction between an electron's magnetic moment and the magnetic field produced by its orbital motion. This coupling is quantitatively analyzed using Dirac's Equation, demonstrating that its effects are proportional to the velocity of the electron relative to the speed of light (v/c). LS coupling significantly influences the fine structure of atomic spectra, particularly in multi-electron systems, and requires a solid understanding of angular momentum to fully grasp energy shifts associated with this phenomenon.

What do you know about the theorem of Clebsch-Gordan...?

Daniel.
 
Briefly, in atomic physics, LS or spin-orbit coupling comes from the interaction of the electron's magnetic moment with the magnetic field generated by the orbital motion. A rigorous approach to the LS coupling starts with Dirac's Eq., and shows that the coupling is of order v/c. Thus, typically LS coupling effects contribute to the fine structure of atomic spectra. Working out the details of LS coupling energy shifts will stretch your angular momentum chops, considerably.

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
