Hartree–Fock Theory for Pseudorelativistic Atoms


We study the Hartree–Fock model for pseudorelativistic atoms, that is, atoms where the kinetic energy of the electrons is given by the pseudo-relativistic operator \(\sqrt{(|{\bf p}|c)^{2} + (mc^{2})^{2}} - mc^{2}\). We prove the existence of a Hartree–Fock minimizer, and prove regularity away from the nucleus and pointwise exponential decay of the corresponding orbitals.
