论文摘要
在存在外部不均匀电场的情况下，已经研究了弱磁热QCD介质中的电荷运输。估计该田间的时空不均匀性很小，因此培养基中的碰撞效应不能忽略，目前估计了由不均匀的电场引起的当前密度（电气和霍尔）。通过采用松弛时间近似和Bhatnagar-krook碰撞核中的相对论鲍尔茨曼方程中的碰撞式互冲突方面。已经探索了电流和霍尔电流密度的磁场，动量各向异性和夸克化学势依赖性，并研究了对各自电导率的影响。该领域的不均匀性被认为对碰撞培养基的电磁反应具有相当大的影响。
The electric charge transport in a weakly magnetized hot QCD medium has been investigated in the presence of an external inhomogeneous electric field. The current densities (electric and Hall)induced by the inhomogeneous electric field have been estimated in the regime where space-time inhomogeneity of the field is small so that the collisional effect in the medium cannot be neglected. The collisional aspect of the medium has been captured by employing both relaxation time approximation and Bhatnagar-Gross-Krook collision kernel in the relativistic Boltzmann equation. The magnetic field, momentum anisotropy, and quark chemical potential dependences of the electric current and Hall current densities have been explored, and the impacts on the respective conductivities have been studied. The inhomogeneities of the field are seen to have sizable effects on the electromagnetic responses of the collisional medium.
