Instability of a Pseudo-Relativistic Model of Matter with Self-
Generated Magnetic Field
(46K, LATeX 2e)
ABSTRACT. For a pseudo-relativistic model of matter, based on the
no-pair Hamiltonian, we prove that the inclusion
of the interaction with the self-generated magnetic
field leads to instability for all positive values of the fine
structure constant. This is true no matter whether this interaction
is accounted for by the Breit potential, by an external magnetic
field which is chosen to minimize the energy, or by the quantized
