On the supersymmetry of the Dirac-Kepler problem plus a Coulomb-type
scalar potential in D+1 dimensions and the generalized Lippmann-Johnson
operator    [PDF]

D. Martinez, M. Salazar-Ramirez, R. D. Mota, V. D. Granados

We study the Dirac-Kepler problem plus a Coulomb-type scalar potential by generalizing the Lippmann-Johnson operator to D spatial dimensions. From this operator, we construct the supersymmetric generators to obtain the energy spectrum for discrete excited eigenstates and the radial spinor for the SUSY ground state
