Interaction energy of superconducting vortices
By means of a constrained variational calculation we determine the interaction energy of two-vortex configurations in the Ginzburg-Landau theory or, equivalently, in the Abelian Higgs model. The…
Experiments with a Gauge Invariant Ising System
Using Monte Carlo techniques, we evaluate the path integral for the four-dimensional lattice gauge theory with a Z/sub 2/ gauge group. The system exhibits a first-order transition. This is contrary…
Monte Carlo Study of Abelian Lattice Gauge Theories
Using Monte Carlo techniques, we study the thermodynamics of four-dimensional Euclidean lattice gauge theories, with gauge groups ${Z}_{N}$ and U(1). For $N\ensuremath{\le}4$ the models exhibit a…

- 15 December 1974
Critical behavior in a class of two-dimensional field theories which exhibit dynamical symmetry breaking at zero temperature is analyzed in the $\frac{1}{N}$ approximation. We show that, in the case…

- 26 November 1984
A quantum Monte Carlo method is developed to treat path integrals at finite temperature and with topological constraints to study a periodic model of a granular superconductor. The results obtained…
Evidence for a new ordered phase in a periodic array of ultrasmall Josephson junctions

- 15 June 1987
The equilibrium properties of a periodic array of Josephson junctions are analyzed using a quantum Monte Carlo method. The model studied includes the effects of Josephson and charging energies in the…
