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.

该奖项支持美国-印度合作研究项目，题为La2-xSrxCuO4 （LSCO）外延薄膜中涡旋态对d波超导性的研究。美国马里兰大学超导研究中心（CSR）的PI Richard Greene和印度坎普尔理工学院（IITK）的Ramesh C. Budhani提出在LSCO外延薄膜的涡旋状态下研究涡旋动力学和准粒子隧穿。利用脉冲激光烧蚀技术制备的高质量定向LSCO外延膜将用于涡旋动力学和隧道效应的测量。漩涡动力学将在IITK进行，隧道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几十年的超导领域的研究人员的经验中汲取优势。两个小组之间现有的协同作用将有助于实现既定的研究目标。
