通过杂质的共振磁通传输
Resonant fluxon transmission through impurities
摘要:
通过不同强度和类型的几种杂质的磁通子传输(即,微短路和微电阻),放置在一个长的约瑟夫森结。阈值钉扎电流的杂质计算作为它们之间的距离,它们的振幅和耗散参数的函数。它示出,因此放置的微短路或微电阻的情况下,阈值钉扎电流表现出一个明确的最小值作为杂质之间的距离的函数。在微电阻器的情况下,接着是微短路,观察到相反的现象,即阈值钉扎电流表现出最大值作为杂质之间的距离的函数。
英文摘要:
Fluxon transmission through several impurities of different strength and type (i.e., microshorts and microresistors), placed in a long Josephson junction is investigated. Threshold pinning current on the impurities is computed as a function of the distance between them, their amplitudes and the dissipation parameter. It is shown that in the case of consequently placed microshorts or microresistors, the threshold pinning current exhibits a clear minimum as a function of the distance between the impurities. In the case of a microresistor, followed by a microshort, an opposite phenomenon is observed, namely the threshold pinning current exhibits maximum as a function of the distance between the impurities.
