具有纵向boost不变性和手征磁效应的反常磁流体力学

Anomalous magnetohydrodynamics with longitudinal boost invariance and chiral magnetic effect

Irfan Siddique, Ren-jie Wang, Shi Pu, Qun Wang

摘要:

本文研究了具有纵向推进不变性的相对论磁流体动力学问题,其中考虑了手征磁效应和有限电导率。在初始磁场与电场平行或反平行的情况下,我们导出了电磁场的解析解以及由初始条件确定的几个参数的展开式中的手征数和能量密度。数值解表明,这种解析解在弱场或大手征涨落情况下也能很好地工作。我们还讨论了实验室坐标系下电磁场的性质。

英文摘要:

We study relativistic magnetohydrodynamics with longitudinal boost invariance in the presence of chiral magnetic effects and finite electric conductivity. With initial magnetic fields parallel or anti-parallel to electric fields, we derive the analytic solutions of electromagnetic fields and the chiral number and energy density in an expansion of several parameters determined by initial conditions. The numerical solutions show that such analytic solutions work well in weak fields or large chiral fluctuations. We also discuss the properties of electromagnetic fields in the laboratory frame.
