The PI will do theoretical research on superconductivity and other properties of granular materials. Studies will be made of the superconductive glass state; the predicted properties of this state have been observed by several groups in samples of high Tc superconducting oxide ceramics, and are the subject of intense theoretical and experimental interest. Other proposed work in superconductivity includes studies of the dynamical properties of superconducting arrays, both ordered and disordered, and with and without an applied magnetic field, and various properties of composite and polycrystalline superconductors. Additional work is proposed in the area of non-linear optical properties but also including the mechanical properties of a composite of a brittle and a ductile material, and on Faraday rotation in granular magnetic materials. The work will be carried out by a variety of methods including numerical simulations, exact analytic results, and mean-field theories.

PI将对颗粒材料的超导性和其他性质进行理论研究。 研究超导玻璃态；几个研究小组已经在高 Tc 超导氧化物陶瓷样品中观察到了这种状态的预测特性，并且是理论和实验领域广泛关注的主题。 其他拟议的超导工作包括研究超导阵列的动态特性（有序和无序、有或没有施加磁场），以及复合材料和多晶超导体的各种特性。 在非线性光学特性领域提出了额外的工作，但也包括脆性和延性材料复合材料的机械特性，以及颗粒磁性材料的法拉第旋转。 这项工作将通过多种方法进行，包括数值模拟、精确分析结果和平均场理论。
