Abstract

We calculate hamiltonian strong coupling expansions to order g^-16 of the vacuum energy and chiral condensate for massless QED with two fermion flavours and a chirally invariant four-fermion interaction. An estimate of the chiral symmetry restoring phase diagram and critical exponents are given, assuming a continuous phase transition.
