Superconducting Arrays, Nonlinear Response, and Other Aspects of the Physics of Inhomogeneous Media

9402131斯特劳德的理论和计算研究将在两个材料研究领域进行。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它们的动力学特性。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。第二个研究领域将是颗粒材料的“经典”非线性特性，特别是非线性光学特性。%将对颗粒状材料的特性进行研究。特别是，将在颗粒状超导体和颗粒状光学材料方面开展工作。这两类材料都有不同寻常的性质，需要从根本上理解，并可能具有重要的技术应用。***

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. ***
