时间相关 Aharonov-Bohm 磁通驱动下介观环中的超电流

The Supercurrent of Mesoscopic Rings Threaded by Time Dependent Aharonov Bohm Flux

利用时间相关ＡｈａｒｏｎｏｖＢｏｈｍ（ＡＢ）型磁通驱动下介观弹道环中单电子波函数的单值性，讨论了含时驱动下环中超电流的周期变化特性。结果表明，时间相关的ＡＢ型磁通（ｔ）可以在环上感应出电场Ｅ（ｔ）≠０，但不影响超电流的幅度大小而仅影响其频率。

The supercurrent of ballistic mesoscopic rings threaded by time dependent flux is discussed by making use of the single valued wave function of Aharonov Bohm problem.It is indicated that the electric field generated by the change in time dependent Aharonov Bohm flux influences the frequency,but not in the amplitude of the supercurrent.
