SO(4) symmetry in the relativistic hydrogen atom
arXiv:0711.0049 · doi:10.1103/PhysRevA.77.034102
Abstract
We show that the relativistic hydrogen atom possesses an SO(4) symmetry by introducing a kind of pseudo-spin vector operator. The same SO(4) symmetry is still preserved in the relativistic quantum system in presence of an U(1) monopolar vector potential as well as a nonabelian vector potential. Lamb shift and SO(4) symmetry breaking are also discussed.
