This paper describes a curious phenomenon: a particle in a rapidly varying potential is subject to an effective magnetic-like force. This force is in addition to the well-known ponderomotive force, but it has not been shown to exist before except for the linear case of a rapidly rotating quadratic saddle potential. We show that this is a universal phenomenon: the magnetic-like force arises generically in potential force fields with rapid periodic time dependence, including but not limited to rotational dependence.

有质洛伦兹力

这篇论文描述了一个奇怪的现象：处于快速变化电位的粒子受到有效的类磁力的影响。这种力是众所周知的有质动力的补充，但除了快速旋转的二次鞍势的线性情况外，它之前没有被证明存在。我们表明这是一个普遍现象：类磁力一般出现在具有快速周期性时间依赖性的势力场中，包括但不限于旋转依赖性。
