超导环电流的研究

Study of current in superconductive rings

以修正的含时金兹堡-朗道理论去研究超导环的超流特性;计算了涡旋运动方程,理论上得到超导环电流是超流量子的整数倍,并且具有多涡旋跳跃;从理论上得到超导环的磁场是量子化的.一定条件下,超流的符号可以发生反转,并且理论上得到了它的表达式.认为超导环是具有对势的对称.

We use a modified time-dependant Ginzburg-Landau model to study the characteristics of superconductive rings and evaluate the vortex motion equations. We show in theory that the flux has jumps, find sign reversal of the current and obtain expressions that are in accordance with the data of experiments.
