论文摘要
基于De Groot-Van leeuwen--van weert对能量弹药和自旋张力张子的定义，用自旋的旋转框架中分析了自由度自由度的传播特性。我们为任意统计的自旋波速度得出分析表达式，并表明它在超偏见的极限中的光速为一半。我们发现，只有横向自由度繁殖，类似于电磁波。最后，我们考虑了耗散校正的效果，并计算了麦克斯韦 - 朱斯特纳统计情况的阻尼系数。
The propagation properties of spin degrees of freedom are analyzed in the framework of relativistic hydrodynamics with spin based on the de Groot--van Leeuwen--van Weert definitions of the energy-momentum and spin tensors. We derive the analytical expression for the spin wave velocity for arbitrary statistics and show that it goes to half the speed of light in the ultra-relativistic limit. We find that only the transverse degrees of freedom propagate, analogously to electromagnetic waves. Finally, we consider the effect of dissipative corrections and calculate the damping coefficients for the case of Maxwell-Jüttner statistics.
