论文摘要
我们介绍了考虑一般相互作用项的狄拉克和Proca领域的不同伪规变化的明确表达。还研究了狄拉克和Proca场与背景电磁场的相互作用的特殊情况。从量子动力学理论开始,从Wigner-runction形式主义造成的碰撞开始,我们为大量的自旋1/2和自旋1颗粒衍生而成,我们建立了不同的伪高分子与相对论的自旋流体动力学之间的联系。讨论了轨道和旋转角动量各种分解的物理意义。
We present the explicit expressions of different pseudo-gauge transformations for Dirac and Proca fields considering a general interaction term. The particular case of the interaction of Dirac and Proca fields with a background electromagnetic field is also studied. Starting from the quantum kinetic theory with collisions derived from the Wigner-function formalism for massive spin-1/2 and spin-1 particles, we establish a connection between different pseudo-gauges and relativistic spin hydrodynamics. The physical implications of the various decompositions of orbital and spin angular momentum are discussed.
