Vacuum State of 2+1 Dimensional SU(2) Lattice Gauge Theory With Fermions and Spontaneous Chiral Symmetry Breaking

  • The vacuum structure of 2 + 1 dimensional SU(2) LGT with fermions is studied by incorporating the exact ground state of pure gauge theory and the variational fermion vacuum state. We have calculated the fermion condensation <ψψ>, and obtained an improved scaling behavior.
