论文摘要
对二维（2D）超导体和介镜薄膜超导装置中磁场和Meissner筛选电流的空间分布的定量理解对于解释这种系统的磁测量结果至关重要。在这里，我们介绍了SuperScreen，SuperScreen是一种开源Python软件包，用于模拟2D超导体对被捕获的通量和应用时间无关的或Quasi-DC磁场的响应，以获取有效的磁穿透深度的任何值，即$λ$。鉴于施加的磁场，SuperScreen使用有效的矩阵反转方法求解了2D伦敦方程，以获取由一个或多个由任意几何的超导薄膜组成的结构内和周围的Meissner电流和磁场。 SuperScreen可用于模拟筛选效果，并计算薄膜超导装置中的自态和相互感应。
Quantitative understanding of the spatial distribution of magnetic fields and Meissner screening currents in two-dimensional (2D) superconductors and mesoscopic thin film superconducting devices is critical to interpreting the results of magnetic measurements of such systems. Here, we introduce SuperScreen, an open-source Python package for simulating the response of 2D superconductors to trapped flux and applied time-independent or quasi-DC magnetic fields for any value of the effective magnetic penetration depth, $Λ$. Given an applied magnetic field, SuperScreen solves the 2D London equation using an efficient matrix inversion method to obtain the Meissner currents and magnetic fields in and around structures composed of one or more superconducting thin films of arbitrary geometry. SuperScreen can be used to model screening effects and calculate self- and mutual-inductance in thin film superconducting devices.
