介观耦合金属环中的持续电流

Persistent currents in mesoscopic coupling metallic ring

在考虑电荷是量子化的基础上,计算了处在外加磁场中的三个有相互耦合作用的介观金属环中的持续电流,分析研究了耦合因素对金属环中持续电流的影响。结果显示,持续电流的幅度不仅受耦合的强度而且还受耦合的相对方向的共同影响。

Numerical simulations and analyses were applied to find the relationships between external magnetic and persistent current of a mesoscopic mutual inductance coupling three rings in accord with the discreteness of electric charge. The influences of an external magnetic filed on the persistent currents of the mesoscopic coupling metallic rings were investigated. The research results indicate that the amplitude of persistent currents in mesoscopic rings depend not only on the coupling intensity but also on coupling direction.
