电荷与磁偶极子的有效相互作用力与Aharonov-Bohm型量子效应的局域性(或非局域性)

Effective interaction force between an electric charge and a magnetic dipole and locality (or nonlocality) in quantum effects of the Aharonov-Bohm type

Gianfranco Spavieri, George T. Gillies, Miguel E. Rodriguez, Maribel Peréz Pirela

摘要:

经典电动力学预见到,运动电荷和磁偶极之间的有效相互作用力会被相互作用场随时间变化的总动量所改变。在麦克斯韦方程组和总动量守恒定律成立的前提下,由总应力-能量张量导出了粒子的运动方程。Aharonov-Bohm型效应的应用表明,所观察到的相移可能是由于有效的本地力所造成的干扰粒子之间的相对滞后。

英文摘要:

Classical electrodynamics foresees that the effective interaction force between a moving charge and a magnetic dipole is modified by the time-varying total momentum of the interaction fields. We derive the equations of motion of the particles from the total stress-energy tensor, assuming the validity of Maxwell's equations and the total momentum conservation law. Applications to the effects of Aharonov-Bohm type show that the observed phase shift may be due to the relative lag between interfering particles caused by the effective local force.
