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

(Revista Matemática Complutense, 2019-06)
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 potentials $\mathbf V$ of Coulomb type: ...
