Abstract
The effects of random dilution of junctions on a two-dimensional Josephson-junction array in a magnetic field are considered. For rational values of the average flux quantum per plaquette f, the superconducting transition temperature vanishes, for increasing dilution at a critical value xS(f), while the vortex ordering remains stable up to xVL>xS, far below the value xp corresponding to the geometric percolation threshold. For xVL<x<xp, the array behaves as a zero-temperature vortex glass. Numerical results for f=1/2 from defect energy calculations are presented and are consistent with this scenario.
