A generalized Coulomb problem for a spin-1/2 fermion
V. B. Mendrot, A. S. de Castro, P. Alberto
We study the Dirac equation in 3+1 dimensions with a general combination of scalar, vector and tensor interactions with arbitrary strengths, all of them described by central Coulom…

Symmetry generators and quantum numbers for fermionic circularly symmetric motion
V. B. Mendrot, A. S. de Castro, P. Alberto
The planar dynamics of spin-1/2 quantum relativistic particles is important for several physical systems. In this paper we derive, by a simple method, the generators for the contin…
