摘要
The (1 + 1)-dimensional Hamiltonian lattice gauge theories and the vacuum structure with fermions are studied analytically by using a unitary transformation and the variational method. The matching of the psi-psiBAR operators in the continuum and on the lattice is discussed. The chiral symmetry is shown to be broken spontaneously. The effect of species doubling is also analyzed. Satisfactory scaling behavior for the chiral order parameter and coincidence with the continuum predictions are obtained.
