Dynamical Symmetries of Dirac Hamiltonian
arXiv:1107.0747 · doi:10.1142/S0217751X12300049
Abstract
Several dynamical symmetries of the Dirac Hamiltonian are reviewed in a systematic manner and the conditions under which such symmetries hold. These include relativistic spin and orbital angular momentum symmetries, SO(4)\times SU_σ(2) symmetry for the Dirac Hydrogen atom, SU(3)\times SU_σ(2) symmetry for the relativistic simple harmonic oscillator. The energy spectrum in each case is calculated from group-theoretic considerations.
