0352598Valls, OriolDescription: This award supports the US-India collaborative research entitled Density Functional Theory of the Mixed State in Layered Superconductors with Pinning. Professors Oriol Valls, University of Minnesota-Twin Cities and Chandan Dasgupta, Indian Institute of Science (IISc), Bangalore will carry out numerical simulations to study the mixed phases of high-temperature superconductors in the presence of various types of random pins. This project is important for understanding the vortex properties in superconductors. The test system is the archetype for studying the effects of quenched disorder on the structure and melting of solids. The density functional approach, which is an original method for studying melting of ordered and disordered vortex systems, has been used successfully by these investigators and is likely to succeed in the present context. This research is very important for applications of superconductivity and could have far-reaching technological and fundamental impacts. Scope: Additionally, it will develop a partnership between a leading US institution and the foremost center for theoretical condensed matter research in South Asia. The PIs are prominent, well-recognized physicists and leaders of the density functional technique. Professor Valls has made important contributions to superconductivity. Students, postdocs and the research groups at both institutions will benefit from this collaboration, which is jointly funded by the Government of India's Department of Science and Technology (DST) under the NSF/DST program.

0352598Valls, Oriol 描述：该奖项支持美印合作研究，题为“具有钉扎的层状超导体中混合态的密度泛函理论”。 明尼苏达大学双城分校的 Oriol Valls 教授和班加罗尔印度科学研究所 (IISc) 的 Chandan Dasgupta 教授将进行数值模拟，研究存在各种类型的随机销的情况下高温超导体的混合相。 该项目对于理解超导体中的涡流特性非常重要。 该测试系统是研究淬火无序对固体结构和熔化影响的原型。 密度泛函方法是研究有序和无序涡旋系统熔化的原始方法，已被这些研究人员成功使用，并且很可能在当前背景下取得成功。 这项研究对于超导的应用非常重要，可能产生深远的技术和基础影响。 范围：此外，它将在美国领先机构和南亚最重要的理论凝聚态研究中心之间建立合作伙伴关系。 PI 是著名的、公认的物理学家和密度泛函技术的领导者。 瓦尔斯教授对超导做出了重要贡献。 两个机构的学生、博士后和研究小组都将从此次合作中受益，该合作由印度政府科学技术部 (DST) 在 NSF/DST 项目下共同资助。
