运动偶极子在一定距离磁场作用下的几何相位

Geometric phase of a moving dipole under a magnetic field at a distance

Kang-Ho Lee, Young-Wan Kim, Kicheon Kang

摘要:

我们预言了在一定距离外有磁场存在时,运动电偶极子的几何量子相移。基于洛伦兹协变场相互作用方法,我们证明了在偶极在无场区运动的条件下,会出现几何相位,这与偶极和场直接重叠所产生的拓扑He-McKellar-Wilkens相位不同.我们讨论了实验的可行性,检测这个阶段与原子干涉,并认为,检测这个阶段将导致更深入地了解量子电磁相互作用的局部性。

英文摘要:

We predict a geometric quantum phase shift of a moving electric dipole in the presence of an external magnetic field at a distance. On the basis of the Lorentz-covariant field interaction approach, we show that a geometric phase appears under the condition that the dipole is moving in the field-free region, which is distinct from the topological He-McKellar-Wilkens phase generated by a direct overlap of the dipole and the field. We discuss the experimental feasibility of detecting this phase with atomic interferometry and argue that detection of this phase would result in a deeper understanding of the locality in quantum electromagnetic interaction.
