Self-Adjoint Extensions for the Dirac Operator with Coulomb-Type Spherically Symmetric Potentials

Biagio Cassano, Fabio Pizzichillo

We describe the self-adjoint realizations of the operator $H:=-i\alpha \cdot \nabla +m\beta +\mathbb{V}(x)$, for $m\in \mathbb{R}$, and $\mathbb V(x)= |x|^{-1} ( ν\mathbb{I}_4 +μβ-i λα\cdot{x…
