Abstract

The analysis of superconducting nanowires placed in different electromagnetic environments is presented in the framework of Ginzburg-Landau model. First domain of application of conducted analysis is noninvasive superconducting detectors of charged particles and robust field induced Josephson junctions. Robust field induced Josephson junctions (rFIJJs) made by polarization of superconducting nanostructures by external magnetic fields are presented in one dimensional model. The analytical methodology of modeling of rFIJJs in one dimensional cases is introduced and possible implementations are pointed by reference to the principle of minimization of magnetic field energy that is preimposing the space dependence of the screening currents. The presented schemes have potential in description both classical and quantum computers with use of topological defects of superconducting order parameter and artificial evolution. Scheme of testing new topologies and working parameters of circuits is given what shall imply enhancement of already known circuit schemes. Furthermore concept of noninvasive superconducting detectors is given as sensing device for moving charged particles as in accelerator beam or in nano-accelerator beam. Obtained results are refereeing to functionalization of superconducting nanowires topology with reference to various programmable biasing magnetic fields that incorporates the concept of programmable superconducting matter. The presented conceptual scheme can also be used for designing the experiments, where Bose-Einstein condensate is being biased with various class of topologies of magnetic fields coming from three dimensional meta-lattice of superconducting nanowires.

摘要

在 Ginzburg-Landau 模型的框架下，对放置在不同电磁环境中的超导纳米线进行了分析。传导分析的第一个应用领域是带电粒子的无创超导探测器和强场感应约瑟夫森结。通过外部磁场极化超导纳米结构制成的强场感应约瑟夫森结 (rFIJJ) 在一维模型中呈现。介绍了在一维情况下对 rFIJJ 进行建模的分析方法，并通过参考磁场能量最小化原理指出了可能的实现方式，该原理预先施加了屏蔽电流的空间依赖性。所提出的方案具有描述经典计算机和量子计算机的潜力，利用超导有序参数和人工进化的拓扑缺陷。给出了测试电路新拓扑和工作参数的方案，这意味着对已知电路方案的增强。此外，非侵入式超导探测器的概念被给出为用于移动带电粒子的传感装置，如在加速器束或纳米加速器束中。获得的结果参考了各种可编程偏置磁场的超导纳米线拓扑的功能化，这些偏置磁场结合了可编程超导物质的概念。提出的概念方案也可用于设计实验，
