New non-unitary representations in a Dirac hydrogen atom
R. P. Martínez-y-Romero, J. Saldaña-Vega, A. L. Salas-Brito
New non-unitary representations of the SU(2) algebra are introduced for the case of the Dirac equation with a Coulomb potential; an extra phase, needed to close the algebra, is als…

Non-unitary representations of the SU(2) algebra in the Dirac equation with a Coulomb potential
R. P. Martínez-y-Romero, A. L. Salas-Brito, Jaime Saldaña-Vega
A novel realization of the classical SU(2) algebra is introduced for the Dirac relativistic hydrogen atom defining a set of operators that, besides, allow the factorization of the…
