U.S.-Argentina Cooperative Research on Joint Research on Basic Properties of Superconductors

该奖项支持由加州大学戴维斯分校的Herman Fink教授和阿根廷巴里洛切原子中心的两名研究人员进行的高温超导体合作研究项目：固体理论小组的Arturo Lopez-Davalos博士和低温实验室的Francisco De La Cruz博士。他们将研究高温超导体的特性以及超导微网络的磁性和临界电流特性。在理论方面，他们将研究在基本金兹堡-朗道方程中包含小相干长度（相干电子对是超导的基础）的影响。这种理论解释是迫切需要的，因为自从发现氮温度超导性以来，在世界范围内产生了爆炸性的实验结果。此外，他们将研究阶梯网络和方形晶格阵列的磁性和临界电流（这些材料最严重的限制是低临界电流）。巴里洛切在超导方面的工作是高质量的，与芬克教授的合作将加强这一努力。阿根廷小组带来了超导体性质的丰富经验，并对该领域的文献做出了许多贡献。以前的协作工作是非常富有成效的。

This award supports a cooperative research project on high-temperature superconductors to be conducted by Prof. Herman Fink of the University of California at Davis and two researchers at the Atomic Center in Bariloche, Argentina: Dr. Arturo Lopez-Davalos, Solid State Theory Group, and Dr. Francisco De La Cruz of the Low Temperature Laboratory. They will investigate the properties of high-temperature superconductors and the magnetic and critical current properties of superconducting micronetworks. On the theoretical side, they will study the effect of the inclusion of a small coherence length (coherent electron pairs are the basis for superconductivity) in the fundamental Ginzburg-Landau equations. Such theoretical interpretation is urgently needed in view of the explosion in experimental results produced world-wide since the discovery of nitrogen-temperature superconductivity. In addition, they will study the magnetic properties and the critical currents (the most severe limitation of these materials is low critical current) of ladder networks and square lattice arrays. The work on superconductivity at Bariloche is of high quality and the collaboration with Prof. Fink will strengthen that effort. The Argentinian group brings vast experience in the properties of superconductors and has made many contributions to the literature in this field. Previous collaborative work has been highly productive.
