Lower bounds on the moduli of three-dimensional Coulomb-Dirac operators via fractional Laplacians with applications

Sergey Morozov, David Müller

For $\nu \in [0,1]$ let $D^{\nu }$ be the distinguished self-adjoint realisation of the three-dimensional Coulomb-Dirac operator $-\mathrm{i}\mathbf{\alpha }\cdot \nabla -\nu |\cdot {|}^{-1}$. For $ν\…
