PHASE-DIAGRAM FOR SPLAY GLASS SUPERCONDUCTIVITY

Localization of flux lines to splayed columnar pins is studied. A sine -Gordon type renormalization group (RG) Study reveals the existence of a splay glass phase and yields an analytic form for the transition te mperature into the glass phase. As an independent test, the I-V charac teristics are determined via a molecular dynamics code. The glass tran sition temperature supports the RG results convincingly. The full phas e diagram of the model is constructed.
