Structural Supercritical Instability of Dirac Electrons in the Field of Two Oppositely Charged Nuclei
Structural Supercritical Instability of Dirac Electrons in the Field of Two Oppositely Charged Nuclei
The Dirac equation for an electron in a finite dipole potential has been studied within the method of linear combination of atomic orbitals (LCAO). The Coulomb potential of the nuclei that compose a dipole is regularized, by considering the finite nuclear size. It is shown that if the dipole momentum …
