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斯特劳德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涉及他们的动态特性，通过求解耦合约瑟夫森方程的过阻尼和欠阻尼阵列。 在层状超导体中，将研究高度各向异性超导体中的磁通晶格熔化。 第二个研究领域是颗粒材料的“经典”非线性性质，特别是非线性光学性质。 %将对粒状材料的性能进行研究。特别是，工作将在粒状超导体和粒状光学材料上进行。 这两类材料都具有不寻常的性质，需要在基本层面上加以理解，并可能具有重要的技术应用。 ***
