论文摘要
我们使用半经典动力学理论研究了弱磁场对有限夸克化学势的热QCD培养基中动量传输的影响。在存在磁场的情况下，动量传输系数获得了张量结构，由五个剪切$ \ weft（η_0，η_1，η_2，η_2，η_3\ right。$ and $ \ left.hout.hout.hout.hout.hout.hout.hout.hout.hout.hout.hout.hout.hout）和两个散装的Viscous Consents $ \ weft（phoft（webt）$ quy_1 $ \ y riry。弱磁场消除了有效的口味质量中的堕落性，从而导致左撇子（L）和右手（R）手性模式的不同质量。系数，$η_0，η_1$和$η_3$在L模式下随着磁场而减小，并增加$ \ Mathrm {r} $模式，而L和$η_2$和$η_4$在L和$ \ MATHRM {rm {r} $模式下增加。大量粘性系数，$ζ_0$和$ζ_1$在L和R模式下增加了磁场。剪切和散装粘性系数用Baryon不对称性积极扩增。
We have investigated the effect of a weak magnetic field on momentum transport in a thermal QCD medium at finite quark chemical potential using a semiclassical kinetic theory. In the presence of a magnetic field, the momentum transport coefficients acquire a tensor structure, reflected by the five shear $\left(η_0, η_1, η_2, η_3\right.$ and $\left.η_4\right)$ and two bulk viscous components $\left(ζ_0\right.$ and $\left. ζ_1\right)$. The weak magnetic field removes the degeneracy in the effective mass of flavours, leading to different masses for the left-handed (L) and right-handed (R) chiral modes of quarks. The coefficients, $η_0, η_1$ and $η_3$ decrease with magnetic field in L mode and increase in $\mathrm{R}$ mode, whereas, $η_2$ and $η_4$ increase in both L and $\mathrm{R}$ mode. The bulk viscous coefficients, $ζ_0$ and $ζ_1$ increase with magnetic field for both L and R mode. The shear and bulk viscous coefficients positively amplify with baryon asymmetry.
