Exceptional coupling constants for the Coulomb-Dirac operator with anomalous magnetic moment
K. M. Schmidt
It was recently shown that the point spectrum of the separated Coulomb-Dirac operator H_0(k) is the limit of the point spectrum of the Dirac operator with anomalous magnetic moment…

Spectral stability of the Coulomb-Dirac Hamiltonian with anomalous magnetic moment
Hubert Kalf, Karl Michael Schmidt
We show that the point spectrum of the standard Coulomb-Dirac operator H_0 is the limit of the point spectrum of the Dirac operator with anomalous magnetic moment H_a as the anomal…
