0532858ShastryDescription: This award supports the U.S.-India Planning Visit: Momentum Dependent Theories for Strongly Correlated Electron Systems. US PI Sriram Shastry, University of California Santa Cruz will visit the Indian Institute of Sciences (IISc), Bangalore to meet with Indian counterpart H.R. Krishnamurthy. They will set up collaboration to study the effect of momentum dependent strong correlations, in an attempt to understand the nature of the fermi surface renormalizations. The problem of strong correlations is widely recognized as a frontier area in condensed matter physics. The work proposed here is of fundamental interest in that it concerns some outstanding problems in condensed matter physics, namely the role of strong correlations in magnetism and superconductivity. Scope: This research deals with an important scientific problem. Professor Krishnamurthy's group at Bangalore is doing computational work that is complementary to the analytical approaches used by Professor Shastry and his group at Santa Cruz and lead to different non-linear numerical schemes. The PIs are both world-class scientists and have successfully collaborated in the past on problems in strongly correlated systems. The proposed effort is a natural extension of the earlier one and of greater scope. The US PI intends to submit the proposal that results from this planning grant to a competition in the Division of Materials Research.

0532858ShastryDescription：该奖项支持美印计划访问：强关联电子系统的动量依赖理论。美国加州大学圣克鲁斯分校的皮里拉姆·沙斯特里将访问班加罗尔的印度科学研究所(IISC)，与印度同行H.R.Krishnamurthy会面。他们将合作研究依赖动量的强关联的影响，试图了解费米表面重整化的本质。强关联问题被广泛认为是凝聚态物理学的前沿领域。这里提出的工作具有根本的意义，因为它涉及凝聚态物理中的一些突出问题，即强关联在磁性和超导中的作用。范围：这项研究涉及一个重要的科学问题。Krishnamurthy教授在班加罗尔的团队正在做的计算工作是对Shastry教授和他在Santa Cruz的团队使用的分析方法的补充，并导致不同的非线性数值格式。这两位PI都是世界级的科学家，过去曾在强关联系统中的问题上成功合作。拟议的努力是先前努力的自然延伸，范围更大。美国PI打算将这一规划拨款的结果提交给材料研究部的一个竞赛项目。
