论文摘要
我们提出了一种在通用媒体中得出动态电磁场有效理论的新方法。它可用于给出具有强磁场的磁性水力动力学（MHD）的系统配方，包括手性物质和Adler-Bell-Jackiw（ABJ）异常的系统。我们在可以忽略速度和温度波动的状态下工作。由此产生的手性异常MHD结合了手性磁效应，手性分离效应，手性电动分离效应以及最近衍生的强场MHD，都在单个连贯的框架中。在线性化水平下，该理论预测手性磁波无法在动态电磁场中存活。由于手性电动分离效果和手性磁效应的动态版本，我们称之为手性磁电射波的不同手性波是出现的。我们预测其波速。我们还引入了一个简单但可解决的非线性模型，以探索手性不稳定的命运。
We present a new way of deriving effective theories of dynamical electromagnetic fields in general media. It can be used to give a systematic formulation of magnetohydrodynamics (MHD) with strong magnetic fields, including systems with chiral matter and Adler-Bell-Jackiw (ABJ) anomaly. We work in the regime in which velocity and temperature fluctuations can be neglected. The resulting chiral anomalous MHD incorporates and generalizes the chiral magnetic effect, the chiral separation effect, the chiral electric separation effect, as well as recently derived strong-field MHD, all in a single coherent framework. At linearized level, the theory predicts that the chiral magnetic wave does not survive dynamical electromagnetic fields. A different chiral wave, to which we refer as the chiral magnetic electric separation wave, emerges as a result of dynamical versions of the chiral electric separation effect and the chiral magnetic effect. We predict its wave velocity. We also introduce a simple, but solvable nonlinear model to explore the fate of the chiral instability.
