项目摘要

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.

0532858Shastry描述：该奖项支持美印计划访问：强相关电子系统的动量相关理论。美国加州大学圣克鲁斯分校首席研究员 Sriram Shastry 将访问位于班加罗尔的印度科学研究所 (IISc)，与印度同行 H.R. Krishnamurthy 会面。他们将建立合作来研究动量依赖的强相关性的影响，试图了解费米表面重整化的本质。强相关性问题被广泛认为是凝聚态物理的前沿领域。这里提出的工作具有根本意义，因为它涉及凝聚态物理中的一些突出问题，即强相关性在磁性和超导性中的作用。范围：这项研究涉及一个重要的科学问题。班加罗尔的 Krishnamurthy 教授的团队正在进行计算工作，该工作与 Shastry 教授及其在圣克鲁斯的团队使用的分析方法相补充，并产生了不同的非线性数值方案。两位 PI 都是世界一流的科学家，过去曾在强相关系统的问题上成功合作。拟议的工作是早期工作的自然延伸，范围更大。美国 PI 打算将本次规划拨款产生的提案提交给材料研究部的竞赛。
