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
  radiation field.
