基于熵流分析，我们建立了一个相对论（准）流体动力学框架，称为回旋流体动力学，来描述强涡度下具有自旋的多体系统的流体动力学。这个框架将最近发展的自旋流体力学推广到自旋密度在导数中处于领先阶，但由于其量子性质而被另一个小参数，普朗克常数，抑制。我们的分析表明，陀螺流体动力学的完全一阶本构关系包含17个输运系数，具有高度的各向异性。
We develop a relativistic (quasi-)hydrodynamic framework, dubbed the gyrohydrodynamics, to describe fluid dynamics of many-body systems with spin under strong vorticity based on entropy-current analysis. This framework generalizes the recently-developed spin hydrodynamics to the regime where the spin density is at the leading order in derivatives but suppressed by another small parameter, the Planck constant ℏ, due to its quantum nature. Our analysis shows that the complete first-order constitutive relations of gyrohydrodynamics involve seventeen transport coefficients and are highly anisotropic.
