论文摘要
相对论磁性水力动力学（RMHD）提供了对各种物理系统中低能长波长现象的极为有用的描述，从重型离子碰撞中的夸克 - 胶子等离子体到超新星，紧凑型恒星和早期宇宙的物质。我们回顾了RMHD的最新理论进展，例如使用熵 - 电流分析的磁通量保存的角度来表达RMHD，非平衡统计操作员方法应用于量子电动力学和相关性动力学理论。我们讨论如何在动力学理论和扰动量子场理论中计算RMHD中的传输系数。我们还探索了RMHD中的集体模式和不稳定性，并特别强调了手性在奇迹中的血浆中的作用。我们还提供了一些RMHD的未来前景，包括与自旋流体动力学的相互作用以及与磁通量保护的新动力学框架的相互作用。
Relativistic magnetohydrodynamics (RMHD) provides an extremely useful description of the low-energy long-wavelength phenomena in a variety of physical systems from quark-gluon plasma in heavy-ion collisions to matters in supernovas, compact stars, and early universe. We review the recent theoretical progresses of RMHD, such as a formulation of RMHD from the perspective of magnetic flux conservation using the entropy-current analysis, the nonequilibrium statistical operator approach applied to quantum electrodynamics, and the relativistic kinetic theory. We discuss how the transport coefficients in RMHD are computed in kinetic theory and perturbative quantum field theories. We also explore the collective modes and instabilities in RMHD with a special emphasis on the role of chirality in a parity-odd plasma. We also give some future prospects of RMHD, including the interaction with spin hydrodynamics and the new kinetic framework with magnetic flux conservation.
