U.S.-India Planning visit: Momentum Dependent Theories for Strongly Correlated Electron Systems

0532858 Shastry描述：该奖项支持美国-印度计划访问：强相关电子系统的动量依赖理论。 加州大学圣克鲁斯分校的美国PI 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.克里希那穆提 他们将建立合作研究动量依赖强关联的影响，试图理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学的前沿领域。 这里提出的工作是根本利益，因为它涉及凝聚态物理学中的一些突出问题，即强关联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。 Krishnamurthy教授在班加罗尔的小组正在进行计算工作，这是对Shastry教授和他在圣克鲁斯的小组所使用的分析方法的补充，并导致不同的非线性数值方案。 两位PI都是世界级的科学家，过去曾在强相关系统的问题上成功合作。 拟议的努力是先前努力的自然延伸，范围更大。 美国PI打算将该计划资助产生的提案提交给材料研究部门的竞赛。

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.
