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：该奖项支持美国印度计划访问：强度相关的电子系统的动量依赖理论。 加利福尼亚大学圣克鲁斯分校的美国Pi Sriram Shastry将访问班加罗尔的印度科学学院（IISC）与印度同行H.R. Krishnamurthy会面。 他们将建立协作以研究依赖动量的强相关性的效果，以了解费米表面重新划定的性质。 强相关性的问题被广泛认为是凝结物理学中的前沿区域。 这里提出的工作具有根本的兴趣，因为它涉及凝结物理学中的一些杰出问题，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（Krishnamurthy）教授的小组正在进行计算工作，这与Shastry教授及其小组在圣克鲁斯（Santa Cruz）所使用的分析方法相辅相成，并导致了不同的非线性数值计划。 PI都是世界一流的科学家，并且过去在过去的问题上成功合作。 拟议的努力是早期范围和更大范围的自然扩展。 美国PI打算将该计划赠款产生的提案提交给材料研究部的竞争。
