Abstract
We study the strongly coupled a-flavor lattice Schwinger model and the SU(2 )-color QCD(2). The strong coupling limit, even with its inherent nonuniver sality, makes accurate predictions of the spectrum of the continuum models and provides an intuitive picture of the gauge theory vacuum. The massive e xcitations of the gauge model are computable in terms of spin-spin correlat ors of the quantum Heisenberg antiferromagnetic spin-1/2 chain.
