U.S.-France Cooperative Research: Interference Effects between Superconducting Vortex Arrays and a Periodic PinningPotential Application to a Frequency-Voltage Converter

这项为期三年的奖项将支持加州大学圣地亚哥分校的伊万·K·舒勒和尼斯大学的阿兰·吉拉伯特在凝聚态物理方面的美法合作研究。他们的研究目的是调查中间有绝缘层的超导层的性质。他们将使用一种中间介质来研究涡旋的耦合，以开发和表征新的超导装置。这位美国研究人员将他在高质量多层超导和磁性材料的样品制备、生长和表征方面的专业知识带到了这次合作中。这与法国调查人员在理论和实验方面的能力是相辅相成的。装置的计算和新材料的测试将在法国进行。超导涡旋的研究对基础研究和应用研究都具有重要意义。这将促进我们对一种新的物质状态的了解，并可能导致超导设备在磁场中性能的改善。

This three-year award will support U.S.-France cooperative research in condensed matter physics between Ivan K. Schuller of the University o California San Diego, and Alain Gilabert of the University of Nice. The objective of their research is to investigate the properties of superconducting layers with an insulating layer between them. They will study the coupling of vortices, using an intervening medium, in order to develop and characterize new superconding devices. The U.S. investigator brings to this collaboration his expertise in sample preparation and growth and characterization of high quality multilayer superconducting and magnetic materials. This is complemented by the French investigator's abilities in theory and experiment. The calculations for the devices and the testing of the new material will occur in France. Studies of superconducting vortices are important to both basic and applied research. This will advance our knowledge of a novel state of matter and could lead to improved performance of superconducting devices in a magnetic field.
