重新审视高斯性：用超导环探索Kibble-Zurek机制
Gaussianity revisited: Exploring the Kibble-Zurek mechanism with superconducting rings
摘要：
在本文中，我们使用在环形超导体的自发磁通产生阐明Kibble-Zurek方案。特别是，我们研究有限的大小和外部领域的影响，这两者都不是直接服从KZ分析。在一维和三维模拟的支持下，超导环的性质被认为是很好地代表了解析高斯近似，间接编码的KZ尺度。在外场存在下的环的实验结果证实了这些发现。
英文摘要：
In this paper we use spontaneous flux production in annular superconductors to shed light on the Kibble-Zurek scenario. In particular, we examine the effects of finite size and external fields, neither of which is directly amenable to the KZ analysis. Supported by 1D and 3D simulations, the properties of a superconducting ring are seen to be well represented by analytic Gaussian approximations which encode the KZ scales indirectly. Experimental results for annuli in the presence of external fields corroborate these findings.
