Higgs algebraic symmetry in the two-dimensional Dirac equation
Fu-Lin Zhang, Bo Fu, Jing-Ling Chen
The dynamical symmetry algebra of the two-dimensional Dirac Hamiltonian with equal scalar and vector Smorodinsky-Winternitz potentials is constructed. It is the Higgs algebra, a cu…

Dynamical symmetry of Dirac hydrogen atom with spin symmetry and its connection with Ginocchio's oscillator
Fu-Lin Zhang, Bo Fu, Jing-Ling Chen
The Dirac hydrogen atom with spin symmetry is shown has a SO(4) symmetry. The generators are derived, and the corresponding Casimir operator leads to the energy spectrum naturally.…

Connection between Coulomb and harmonic oscillator potentials in relativistic quantum mechanics
Bo Fu, Fu-Lin Zhang, Jing-Ling Chen
The Levi-Civita transformation is applied in the two-dimensional (2D) Dirac and Klein-Gordon (KG) equations with equal external scalar and vector potentials. The Coulomb and harmon…
