Possible Glassiness in a Periodic Long-Range Josephson Array
Abstract
We present an analytic study of a periodic Josephson array with long-range interactions in a transverse magnetic field which frustrates the superconducting phases. We find that this system exhibits a first-order transition into a phase characterized by an extensive number of states separated by barriers that scale with the system size; the associated discontinuity is small in the limit of weak applied field, thus permitting an explicit analysis in this regime.
