US-India Cooperative Research: Investigation of the Superelectron Density at the Superconductor-Insulator(SI) Transition in Two Dimensions

0216755戈德曼描述：该奖项支持美国和印度的合作研究，题为调查超导体-绝缘体(SI)转变的二维超电子密度。美国明尼苏达大学理工学院物理学特聘教授皮艾伦·戈德曼将与印度科学研究所(IISC)N·钱德拉塞卡尔(N.Chandrasekhar)启动一项合作研究计划。高盛的NSF支持的研究重点是限制在平面(2D)内的电子的性质，特别是极端2D极限下的超导电性，在这种极限下，存在量子临界行为和2D中金属状态的存在问题。Chandrasekhar的努力集中在类似的问题上，但有具体的试验性调查，这与高盛的不同。他们提议联合起来，对各自更广泛项目的子集进行调查。范围：这项研究将为这两个研究项目增加一个国际层面，并将极大地加快SI转变附近超流体密度测量的研究进展。这项合作将加强这两个机构的研究生和博士后的培训，并促进IISC(Ramakrishnan)和明尼苏达州(Larkin和Glazman)凝聚态理论方面的强大群体之间的互动。这些人都是世界级的理论家。高盛的研究项目在青年科学家的培养方面非常强大。这项活动由印度科技部(DST)在NSF/DST联合计划下提供支持。

US PI Allen Goldman, Institute of Technology Distinguished Professor of Physics, University of Minnesota will start a collaborative research program with N. Chandrasekhar, Indian Institute of Science (IISc). Goldman's NSF supported research focuses on properties of electrons confined to a plane (2D), particularly superconductivity in the extreme 2D limit, where there are issues of quantum critical behavior and the existence of a metallic state in 2D. Chandrasekhar's efforts are concentrated on similar problems, but with specific experimental investigations, which differ from Goldman's. They propose to join forces to carry out investigations on a subset of their respective broader programs. Scope: This research will add an international dimension to both research programs and will greatly speed the progress of research on measurements of the superfluid density near the SI transition. The collaboration will enhance the training of graduate students and postdocs at both institutions and promote interaction between the powerful groups in condensed matter theory at the IISc, (Ramakrishnan) and at Minnesota (Larkin and Glazman). These individuals are world-class theoreticians. Goldman's research program is very strong in the development of young scientists. This activity is supported by the Indian Department of Science & Technology (DST) under the NSF/DST joint program.
