9402131 Stroud Theoretical and computational studies will be done in two areas of materials research. The first area involves studies of two types of weakly coupled superconducting systems: (i) Josephson arrays and (ii) layered superconductors. The bulk of the Josephson array work will involve their dynamic properties by solving the coupled Josephson equations for overdamped and underdamped arrays. In layered superconductors studies will be made of flux lattice melting in highly anisotropic superconductors. The second area of research will be "classical" nonlinear properties of granular materials, in particular, nonlinear optical properties. %%% Research will be done on the properties of granular materials. In particular, work will be done on granular superconductors and on granular optical materials. Both classes of materials have unusual properties which need to be understood on a fundamental level and which could have important technological applications. ***

9402131 Stroud 理论和计算研究将在材料研究的两个领域进行。 第一个领域涉及两种类型的弱耦合超导系统的研究：（i）约瑟夫森阵列和（ii）层状超导体。 约瑟夫森阵列的大部分工作将通过求解过阻尼和欠阻尼阵列的耦合约瑟夫森方程来涉及其动态特性。 在层状超导体中，研究将涉及高度各向异性超导体中的通量晶格熔化。 第二个研究领域是颗粒材料的“经典”非线性特性，特别是非线性光学特性。 %%%将对颗粒材料的特性进行研究。特别是，将在粒状超导体和粒状光学材料上开展工作。 这两类材料都具有不寻常的特性，需要从根本上理解这些特性，并且可能具有重要的技术应用。 ***
