| 摘 要： | 利用电磁对偶原理与洛伦兹力矩的交叉耦合形式,重新对阿哈罗诺夫-凯什(Aharonov-Casher)效应产生的物理机制进行了解释.计算出了运动磁矩与电场之间的交叉耦合力矩、电磁系统的拉氏函数及正则动量.由此推出了带有磁矩的原子(属于中性粒子)在电场中的等效势能,该势能影响到了微观粒子波函数的位相,使得粒子的德布罗意波的衍射图样发生变化.因此从理论上得出:A-C效应中几何位相的移动,还存在物理来源,即交叉耦合力矩.

| Abstract: | Using dual principle of electromagnetic field and the cross coupling form of Lorentz moment,the physical mechanism which results in Aharonov-Casher(A-C) effect has been newly explained.It's that the cross coupling moment between moving magnetic moment and electric field,the Lagrangian function and canonical momentum of electromagnetic system are calculated in this paper.From this,equivalent potential energy of atom(belong to neutral particle) with moving magnetic moment is deduced.The potential energy affects phase of wave function of microscopic particle,enables the de Broglie wave of particle to change its diffraction pattern.So it can be deduced theoretically that the geometry phase shift in A-C effect still has physics origin,i.e.the cross coupling moment. |
