The phase transition kinetics of Ising gauge models are investigated. Despite
the absence of a local order parameter, relevant topological excitations that
control the ordering kinetics can be identified. Dynamical scaling holds in the
approach to equilibrium, and the growth of typical length scale is
characteristic of a new universality class with L(t)∼(t/lnt)1/2. We suggest that the asymptotic kinetics of the 2D Ising gauge
model is dual to that of the 2D annihilating random walks, a process also known
as the diffusion-reaction A+A→inert.Comment: 10 pages in Tex, 2 Postscript figures appended, NSF-ITP-93-4
