    A renormalisation group technique for spin and gauge systems with topological excitations
    (American Physics Society, 1982) Aldazabal, Gerardo Marcelo; Parga, N. O.
    We present a real space renormalisation group technique able to deal explicitly with gases of topological excitations. As examples we consider the two-dimensional X Y model and the three-dimensional compact electrodynamics.

    Wilson loop Langevin equations for U (1) lattice gauge theory.
    (American Chemical Society, 1983) Aldazabal, Gerardo Marcelo; Dagotto, E.; González Arroyo, A.; Parga, Nestor Omar
    We study the stochastic quantization for lattice QED and derive the corresponding Langevin equations for the Wilson loops. The equivalence with the usual quantization procedure is established in the framework of strong coupling perturbation theory showing that the Wilson loop stochastic equations become the Schwinger-Dyson equations for the loops when the system reaches its equilibrium distribution.
