US-India Cooperative Research: Theoretical Studies on Magnetoresistive Oxides

0002745 MahantiDescription：该材料研究奖授予美国-印度合作研究：磁阻氧化物的理论研究。 S.D.教授密歇根州立大学的Mahanti和印度Kharagpur理工学院的Arghya Taraphder将研究磁阻氧化物的电子结构。研究将集中在锰氧化物和双钙钛矿的现实模型系统的构建上。他们将把哈特里-福克计算的结果与更容易处理的理论模型的结果联系起来。 研究人员认识到Hartree-Fock和局域自旋密度近似在电子结构工作中的优势和局限性，并计划使用这两种方法来学习单独使用这两种方法可能无法学到的东西。 这些结果在凝聚态物理中具有广泛的应用价值。适用范围：氧化物材料仍然是美国一个充满活力的研究领域，研究人员有着出色的记录，对该领域做出了许多重要贡献，他们的合作可能会带来广泛有趣的结果。 与印度理工学院的联系，Kharagpur是优秀的，在这两个机构的学生将受益于科学家的交流。 该奖项是与印度政府科学技术部共同支持的。

0002745MahantiDescription: This award in materials research is for US-India Cooperative Research: Theoretical Studies on Magnetoresistive Oxides. Professor S.D. Mahanti of Michigan State University and Indian collaborator Arghya Taraphder of the Indian Institute of Technology, Kharagpur will study the electronic structure of magnetoresistive oxides.The research will focus on construction of realistic model systems for manganites and double perovskites. They will relate the results of Hartree-Fock calculations to those of more tractable theoretical models. The investigators recognize the strengths and limitations of Hartree-Fock and local spin density approximations in electronic structure work, and plan to use both to learn what might not be learned from either alone. The results are expected to have wide applicability in condensed matter physics. Scope: Oxide materials continue to represent a vigorous area of research in the U.S. The investigators have excellent track records, have made many important contributions to the field, and their collaboration is likely to lead to broadly interesting results. The connection with the Indian Institute of Technology, Kharagpur is excellent and the students at both institutions will benefit from the exchange of scientists. This award is supported jointly with the Government of India's Department of Science and Technology.
