Abstract
The ground-state and thermal properties of a two-dimensional array of Josephson coupled superconducting wires is studied. For rational values of the magnetic flux per plaquette, mean-field theory provides an accurate description and the system makes a transition to a vortex state. For small values of the magnetic flux per plaquette, mean-field theory also provides an adequate description. The measurement of critical currents can provide information on the ground state.
