Physics of Strong Disorder and Correlation

理解强相互作用的电子系统是凝聚态物理的主要目标之一。许多重要的物理现象都是由强相关产生的，包括所有的磁性、金属-绝缘体转变、莫特转变和高温电导率。随着新材料和新现象的不断发现，凝聚态物理是一个充满活力和令人兴奋的科学领域。理论工作既需要解释实验发现，也需要指导对新材料和新现象的探索。这个研究项目是我们在这个大方向上继续努力的继续。我们提出的具体工作集中在理解莫特跃迁附近的量子磁性，以及它与高温超导性和一类新的钴氧化物超导体的关系。如上所述，提议的活动解决了物理学中的一些关键问题，当然具有重要的智力价值。本课题的研究成果涉及新材料和新现象，将对物理和材料科学产生广泛的影响。此外，首席研究员在与学生和博士后合作方面有着出色的记录。

The understanding of strongly interacting electronic systems is one of the primary goals of condensed matter physics today. Many important physical phenomena arise from strong correlation, including all of magnetism, metal-insulator transitions, the Mott transition and high temperature conductivity. With the constant stream of discovery of novel materials and new phenomena, condensed matter physics is a vibrant and exciting area of science.Theoretical work is needed both to interpret experimental discoveries and to guide the search for new materials and new phenomena. This research project is a continuation of our effort to carry on work in this general direction.The specific work we propose focuses on the understanding of quantum magnetism in the vicinity of the Mott transition, and its relationship to high temperature superconductivity and a new class of cobalt oxide superconductors.As stated above, the proposed activity addresses some of the key issues in physics and certainly holds significant intellectual merit. Results of the proposed research will have broad impact on physics and materials science in that they relate to new materials and novel phenomenon. In addition, the principal investigator has an excellent record working with students and postdoctoral associates.
