摘    要:本文导出了电子在电磁场中合AC效应的哈密顿量,结果比Aharonov-Casher的中子哈密顿多了1/2因子,应用到同时存在AB,AC效应的介观环中,精确求出了能诣,持续电流,自旋流的解析表达式。讨论了T=0K时AC效应诱发的持续流,在强电场下,AC效应有极重要影响。

关 键 词:介观环,AC效应,持续流

Abstract:An effective Hamiltonian describing AC effect for electrons in electromagnetic field isderired and a factor of 1/2 over Anaronov-Casher Hamiltonian is obtained. Based on an exactsecond guantized Hamiltonian of non-interacting electron gas in the mesoscopic ring mixed withAB,AC effect,analytic solutions for energy eigenvalues, the persistent current and Dersistentspin curreut are obtained It is shown that AC effect is extremely important for electrons in somesemiconductors applied with intense electric field.
Keywords:mesoscopic ring  AC effect  persistent current
