Abstract

We review the key steps of the relativistic fluid dynamics formalism with spin degrees of freedom initiated recently. We obtain equations of motion of the expansion of the system from the underlying definitions of quantum kinetic theory for the equilibrium phase space distribution functions. We investigate the dynamics of spin polarization of the system in the Bjorken hydrodynamical background.
流体力学形式与自旋动力学
我们回顾了最近提出的具有自旋自由度的相对论流体动力学形式化的关键步骤。从平衡相空间分布函数的量子动力学基本定义出发,得到了系统膨胀的运动方程。我们研究了系统在比约肯流体动力背景下的自旋极化动力学。
