9704972 Joynt This grant will support the work of this mid-career theorist in three different projects in the general area of strongly correlated electrons. Continuing the PI's work on supercondictivity of heavy fermions, the first project contains a study of the expected effects in neutron scattering from a flux lattice. In the second project based on the properties high Tc superconductors, there are two sub- projects: (1) Properties of a twin boundary junction and a proximity effect junction and (2) a variational study of disorder on a "d-wave"superconductor. Finally, there are plans to study the properties of a liquid crystal like state in quantum Hall effect. %%% This grant to mid-career theorist supports work in several projects related to the properties of some curious superconductors, all discovered during the Eighties. They include alloys of Uranium and Platinum, where the PI pioneered with some early work on the unconventional superconducting properties. They also include the better known high Tc materials where again the PI made some early conjectures about some special effects and which survive a closer scrutiny in more recent years. Much of the work proposed here builds on this very creative and original PI's earlier successes. ***

9704972乔恩特，这笔赠款将支持这位职业生涯中期的理论家在强关联电子一般领域的三个不同项目中的工作。继续PI关于重费米子超导性的工作，第一个项目包含了对通量晶格中中子散射的预期效应的研究。在第二个项目中，根据高温超导体的性质，有两个子项目：(1)孪晶边界结和邻近效应结的性质；(2)“d波”超导体无序的变分研究。最后，计划研究量子霍尔效应中类液晶态的性质。这笔给职业生涯中期理论家的拨款支持了几个项目的工作，这些项目都是在80年代发现的，这些项目都与一些奇怪的超导体的性质有关。它们包括铀和铂的合金，在这些合金中，PI率先在非传统超导性能方面进行了一些早期工作。它们还包括更知名的高T_c材料，PI再次对一些特殊效果进行了早期猜测，并在最近几年经受住了更密切的审查。这里提出的许多工作都建立在这个非常有创意和原创的PI早期的成功基础上。***
