论文摘要
我们介绍了非亚伯血浆中手性等离子体不稳定性和轴向电荷转移的第一原理研究，并通过执行$ 3+1 $ d实时的经典经典式晶格模拟和动态费米子，并通过执行$ 3+1 $ d实时的经典经典效果模拟，并通过执行$ 3+1 $ d实时的经典经典效果模拟。我们首次明确证明了与阿贝尔血浆不同的是，手性从物质部门转移到量规场，主要是由于拓扑Sphaleron的过渡。我们详细介绍了冷abelian $ u（1）$和非阿布莱恩$ su（2）$等离子体中轴向电荷动力学的相似性和差异，并评论了我们对研究异常运输现象的发现的含义，例如QCD中的手性磁效应。
We present a first principles study of chiral plasma instabilities and axial charge transfer in non-Abelian plasmas with a strong gauge-matter coupling $g^2N_f=64$, by performing $3+1$ D real-time classical-statistical lattice simulation with dynamical fermions. We explicitly demonstrate for the first time that -- unlike in an Abelian plasma -- the transfer of chirality from the matter sector to the gauge fields occurs predominantly due to topological sphaleron transitions. We elaborate on the similarities and differences of the axial charge dynamics in cold Abelian $U(1)$ and non-Abelian $SU(2)$ plasmas, and comment on the implications of our findings for the study of anomalous transport phenomena, such as the chiral magnetic effect in QCD matter.
