这种理论研究的重点是强相关的系统，连同课件开发和传播和研究相关代码的文件。 研究将涉及继续发展集群平均场技术，并将集中在非常规超导体，如铜酸盐和有机超导体，无序的影响，自旋轨道耦合和自旋电子材料GaMnAs的相关性，以及非本地相关性对耗尽和铁磁性的影响重费米子材料。 相关计算将在大规模并行计算机上进行。 将继续开发相关的科学课件。 科学和教育成果将在网上随时公布，研究涉及具有重大科学和社会影响的领域。 超导性具有重要的应用，例如医疗诊断设备和超高性能电子通信滤波器。 如果转变温度足够高，则可能有更多的用途。 铁磁半导体对于自旋电子器件的发展具有很大的前景，其中电子电荷和自旋都用于具有新功能的器件中。 在重费米子材料中，铁磁性的耗尽和起源的作用仍然是人们非常感兴趣甚至有争议的话题。 正在发展的团簇平均场形式主义具有从相关有序系统到无序材料的广泛应用。除了在物理学期刊上发表结果外，通过开发具有广泛应用的新计算算法，更直接的方式是在PI的网站和公共科学软件库（如MCC）上分发这些代码的示例软件存档。 分布式代码包括解析连续的最大熵代码，以及动态平均场和动态簇量子蒙特卡罗codes.Education被大量集成到这个项目中，通过研究生的支持，鼓励他们参加会议，更重要的是通过NSF赞助的课件在网站上分发的开发。 提供两门完整的课程，用于教授高级本科课程以及固态物理和电动力学的入门研究生课程。 除了通常的材料，这些课程强调现代计算技术。 演示计算机在科学中最基本用途的课程正在为初中和高中开发。 参加辛辛那提“探究式物理”项目的市内公立学校教师将在夏季学习使用该软件，并在国家科学基金会资助的研究生的协助下，在秋季将其带回给学生。这种理论研究的重点是强相关的系统，连同课件开发和传播和研究相关代码的文件。 教育被大量融入到这个项目中，既通过研究生的支持，鼓励他们参加会议，更重要的是通过开发在网站上分发的NSF赞助的课件。 正在为初中和高中开发演示计算机在科学中最基本用途的课程。

The focus of this theoretical research is on strongly correlated systems, together with courseware development and the dissemination and documentation of research related codes. The research will involve the continued development of cluster mean field techniques and will focus on unconventional superconductors such as the cuprates and organic superconductors, the effect of disorder, spin-orbit coupling and correlations in the spintronic material GaMnAs, and the effect of non-local correlations on exhaustion and ferromagnetism in heavy Fermion materials. The related calculations will be carried out on massively parallel computers. Related scientific courseware will continue to be developed. Scientific and educational results will be readily accessible on the web.The research addresses areas of significant scientific and social impact. Superconductivity has important applications, such as medical diagnostic equipment and ultra-high-performance electronic communication filters. Many more uses are possible if the transition temperatures are high enough. Ferromagnetic semiconductors have great promise for the development of spintronic devices where both the electronic charge and spin are used in devices with new functionalities. The role of exhaustion and origin of ferromagnetism in heavy Fermion materials remain topics of great interest and even controversy. The cluster mean field formalism being developed has broad applications from correlated ordered systems to disordered materials.Apart from the publication of results in physics journals, the impact of this research is enhanced through the development of new computational algorithms with broad applications, and more directly through the distribution of examples of these codes on the PI's website and on public repositories of scientific software such as the MCC Software Archive. Distributed codes include Maximum Entropy codes for analytic continuation, and dynamical mean field and dynamical cluster Quantum Monte Carlo codes.Education is heavily integrated into this project, both through the support of graduate students, encouraging them to attend meetings, and more importantly through the development of NSF-sponsored courseware distributed on the website. Two complete courses are available, which are used to teach both upper-level undergraduate courses as well as introductory graduate courses in Solid State Physics and Electrodynamics. In addition to the usual materials, these courses emphasize modern computational techniques. Courseware that demonstrates the most basic use of computers in science is being developed for middle and high school. Inner-city public school teachers who participate in the "Physics by Inquiry" programs at Cincinnati will learn to use it during the summer, and bring it back to their students in the fall, assisted by NSF-supported graduate students.%%% The focus of this theoretical research is on strongly correlated systems, together with courseware development and the dissemination and documentation of research related codes.
