A Hardy-type inequality and some spectral characterizations for the Dirac-Coulomb operator

Biagio Cassano, Fabio Pizzichillo, Luis Vega

We prove a sharp Hardy-type inequality for the Dirac operator. We exploit this inequality to obtain spectral properties of the Dirac operator perturbed with Hermitian matrix-valued…

Boundary triples for the Dirac operator with Coulomb-type spherically symmetric perturbations

Biagio Cassano, Fabio Pizzichillo

We determine explicitly a boundary triple for the Dirac operator $H := - i α \cdot \nabla + m β + V (x)$ in $R^{3}$ , for $m \in R$ and $\mathbb V(x)= |x|^{-1} ( ν\mathb…
