论文摘要
由自旋轨道相互作用引起的异常洛伦兹转化中的侧面跳跃在各种有趣的物理学中起着重要作用,例如手性涡旋效应和自旋极化。在这项工作中,很少讨论并评估了很少讨论的旋转半颗粒的侧跳。得出了描述这种侧跳的紧凑分析表达,并发现在无质量极限内描述手性费米子的表达。进一步证明,在考虑到获得的侧跳后,将恢复总角动量的协方差,该协方差将通过正常的洛伦兹转化而损坏。
The side jump in the anomalous Lorentz transformation, arising from the spin-orbit interactions, plays important roles in various intriguing physics, such as chiral vortical effects and spin polarization. In this work, the side jump of the spin-half massive particles, which has rarely been discussed, is visualized and evaluated for the first time. A compact analytical expression describing such side jumps is derived, and found approaching the one describing the chiral fermions in the massless limit. It is further demonstrated that the covariance of the total angular momentum, which would be broken by a normal Lorentz transformation, is restored after the obtained side jumps are taken into account.
