论文摘要
使用自由度自由度的经典描述，我们将最新的用于自旋流体流体的完美流体流体动力学的配方扩展到包括耗散的病例。我们的工作基于对具有自旋1/2的大规模颗粒的经典动力学方程的分析，并在松弛时间近似中处理了碰撞项。动力学理论框架确定了粘性和扩散术语的结构，并允许明确计算一组完整的新动力学系数，这些系数表征了耗散性旋转动力学。
Using classical description of spin degrees of freedom, we extend recent formulation of the perfect-fluid hydrodynamics for spin-polarized fluids to the case including dissipation. Our work is based on the analysis of classical kinetic equations for massive particles with spin-1/2, with the collision terms treated in the relaxation time approximation. The kinetic-theory framework determines the structure of viscous and diffusive terms and allows to explicitly calculate a complete set of new kinetic coefficients that characterize dissipative spin dynamics.
