摘要
采用半经典理论方法 ,对旋转超导体内的电流和电磁场进行理论分析 .在把非惯性力场等效为真实力场并假设其适用于量子力学的基础上 ,获得超导电子所满足的薛定谔方程和概率密度流表达式 .发现超导电子的正则动量和空间相位的梯度有正比例的关系 ;发现在没有外电场和外磁场情况下 ,匀速转动的超导体内出现净电荷电场、磁场 ,表面出现净电荷及超导电流 .
In this paper ,we study the current and the electromagnetic field in a rotating superconductor through semiclassical approach. A Schrdinger wave equation and probability density current of superelectrons have been obtained. It is found that the canonical momentum is directly proportional to the gradient of space phase.We also find an electric field and a magnetic field together with the superconducting current generated in a uniformly rotating superconductor even without an external electromagnetic field.
