Dirac哈密顿量的动力学对称性
Dynamical Symmetries of Dirac Hamiltonian
摘要:
几个动力学对称性的狄拉克哈密顿系统的方式和条件下,这种对称性举行。其中包括相对论性自旋和轨道角动量对称性、狄拉克氢原子的SO(4)\times SU_σ(2)对称性、相对论性简谐振子的SU(3)\times SU_σ(2)对称性。在每种情况下的能谱计算从群论的考虑。
英文摘要:
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.
