手征磁效应和反常输运的实时晶格模拟

Chiral magnetic effect and anomalous transport from real-time lattice simulations

Niklas Mueller, Sören Schlichting, Sayantan Sharma

摘要:

我们提出了第一原理研究异常诱导的输运现象进行实时晶格模拟与动力学费米子同时耦合到非阿贝尔$SU(N_c)$和阿贝尔$U(1)$规范场。研究了在外加磁场作用下的闪锌矿相变过程中矢量电流和轴向电流的行为,证明了手征磁场(CME)和手征分离效应(CSE)的相互作用是如何导致传播波的形成的.我们进一步分析了有限夸克质量引起的明确的手征对称性破缺量对感应矢量流的大小和波的传播的依赖性。

英文摘要:

We present a first-principle study of anomaly induced transport phenomena by performing real-time lattice simulations with dynamical fermions coupled simultaneously to non-Abelian $SU(N_c)$ and Abelian $U(1)$ gauge fields. Investigating the behavior of vector and axial currents during a sphaleron transition in the presence of an external magnetic field, we demonstrate how the interplay of the Chiral magnetic (CME) and Chiral separation effect (CSE) lead to the formation of a propagating wave. We further analyze the dependence of the magnitude of the induced vector current and the propagation of the wave on the amount of explicit chiral symmetry breaking due to finite quark mass.
