Abstract
A model is used to show that a Josephson-junction array in an irrational magnetic field undergoes a glass transition for finite cooling rate. At zero temperature the resultant glassy state possesses a nonzero critical current. The low-temperature behavior of the system can be modeled by a spin-wave theory. The relevance of these results for real experiments on arrays is discussed.Keywords
