摘要: 近些年来量子力学中的相位问题在凝聚态物理学中扮演着至关重要的角色,比如Aharonov-Bohm 效应, Aharonov-Caser效应和Berry相位.这里我们根据电磁的对偶性,提出一个运动电偶极矩在磁场中也能产生类Aharonov- Caser效应.同时,我们还从数学角度指出产生这些量子力学的相位效应的根源是来自于运动系统中的势能不仅是位置的函 数,而且还是速度的函数.因此,根据我们的结论可以设计全新的物理模型来实现新型的量子力学相位效应.

Abstract: The issue of phases in quantum mechanics plays a vital role in condensed matter physics in recent years,such as Aharonov-Bohm effect and Aharonov-Caser effect,as well as Berry phase.Here,we propose the counterpart of Aharonov-Caser effect can be realized in a system with a motion of electric dipole based on the electric-magnetic duality. In addition,we also propose the emergence of quantum phases stems from generalized velocity dependent potential.Thus,our findings should provide an avenue to design the models to realize the exotic quantum phases in future.
