摘要

We investigate stability of matter of the Hartree-Fock functional of the relativistic electron-positron field -- in suitable second quantization -- interacting via a second quantized Coulomb field and a classical magnetic field. We are able to show that stability holds for a range of nuclear charges $Z_1,..,Z_Kleq Z$ and fine structure constants $lpha$ that include the physical value of $lpha$ and elements up to holmium ($Z=67$).
