Abstract
A bstract We derive an effective action for charged plasmas with an anomalous (abelian) global current charge current using holography. The holographic description is captured by the dynamics of an Einstein-Maxwell-Chern-Simons theory in an asymptotically AdS spacetime. The ’t Hooft anomaly contribution, which is encoded in the Chern-Simons term, contributes at the Gaussian order in the effective action only in the momentum diffusion sector, where it leads to chiral shear waves. However, as we demonstrate, beyond the Gaussian order, there is non-trivial imprint of the parity-violating anomaly term in sound and charge diffusion dynamics as well.
本文利用全息技术推导了带电等离子体具有异常(阿贝尔)全局电流的有效作用。全息描述是由爱因斯坦-麦克斯韦-陈-西蒙斯理论在渐近AdS时空中的动力学捕获的。在chen - simons项中编码的' t Hooft异常贡献仅在动量扩散扇区的有效作用中以高斯阶贡献,在该扇区导致手性横波。然而,正如我们所证明的,在高斯阶之外,在声音和电荷扩散动力学中也存在违反宇称的异常项的非平凡印记。
