US-India Cooperative Research: Studies of the Vortex State vis-a-vis d-wave Superconductivity in Epitaxial Films of La2-xSrxCuO4

0242867Greene该奖项支持美国和印度的合作研究项目，题为La2-xSrxCuO4(LSCO)外延薄膜中涡旋态与d波超导电性的研究。马里兰大学超导研究中心(CSR)的美国皮理查德·格林和印度理工学院坎普尔(IITK)的拉梅什·C·布达尼(Ramesh C.Budhani)提议研究LSCO外延薄膜涡旋态的涡旋动力学和准粒子隧道效应。采用脉冲激光烧蚀技术制备的LSCO高质量定向外延薄膜将用于涡旋动力学和隧道效应的测量。虽然漩涡动力学将在IITK进行研究，但隧道效应的测量将在马里兰大学进行。这项研究从每个机构最先进的研究设施和研究人员在超导领域数十年的经验中汲取了力量。这两个小组之间现有的协同作用将有助于实现所述研究目标。

0242867Greene This award supports the US-India collaborative research project entitled Studies of the Vortex State vis-'a-vis d-wave Superconductivity in Epitaxial Films of La2-xSrxCuO4 (LSCO). US PI Richard Greene of the Center for Superconductivity Research (CSR), University of Maryland and Ramesh C. Budhani of the Indian Institute of Technology Kanpur (IITK) propose to study vortex dynamics and quasiparticle tunneling in the vortex state of LSCO epitaxial films. High quality and oriented epitaxial films of LSCO deposited with the technique of pulsed laser ablation will be used for measurements of vortex dynamics and tunneling. While vortex dynamics will be addressed at the IITK, measurements of tunneling will be undertaken at the University of Maryland. This research draws strengths from the state-of-the-art research facilities at each institution and decades of experience of the investigators in the field of superconductivity. The existing synergy between the two groups will facilitate realization of the stated research objectives.
