| 摘 要： | 基于含时Ginzburg-Landau（TDGL）方程建立二维超导薄膜经历快速冷却后的拓扑缺陷数目与冷却速度的关系模型.采用差分法对此模型进行了数值模拟,计算出不同冷却速度下拓扑缺陷数目随着时间的变化关系.计算结果发现,在不同冷却速度下,缺陷数目随着时间的变化可以分为两个阶段：第一阶段缺陷数目较多,拓扑缺陷数目随时间急...

| Abstract: | A model was build about the relation of the numbers of topological defects and cooling rate during a rapid quench in two-dimension superconducting films based on Time-Dependent Ginzburg-Landau(TDGL).We present numerical solutions of the model by a difference approximation,and compute the numbers of topological defects changing with time during different cooling rates.The results show that the curve of the numbers of topological defects changing with time during different cooling rates can be divided into tw... |
