Gauge fields on a lattice. II. Gauge-invariant Ising model
Abstract
We study the case of a discrete local gauge group Z2 in order to discuss the existence of a transition in dimension d>=3. We compute the critical constant for d=3 and 4 and show that in three dimensions the transition is a second-order one.
