论文摘要
考虑到强场的近似，我们计算有限温度的硬热环压力以及热和密集的QCD物质在最低兰道水平下以一环顺序计算。我们考虑在强磁场存在的情况下，即沿平行和垂直于磁场方向的纵向和横向压力。首先，我们计算并讨论了最低兰道水平上QCD物质的各向异性夸克数易感性。发现纵向夸克数的敏感性随温度而增加，而横向的易感性随温度而降低。我们还计算弱场近似中的夸克数敏感性。我们发现，在弱场近似中，对夸克数易感性的热磁化校正非常小。
Considering the strong field approximation we compute the hard thermal loop pressure at finite temperature and chemical potential of hot and dense deconfined QCD matter in lowest Landau level in one-loop order. We consider the anisotropic pressure in the presence of the strong magnetic field i.e., longitudinal and transverse pressure along parallel and perpendicular to the magnetic field direction. As a first effort, we compute and discuss the anisotropic quark number susceptibility of deconfined QCD matter in lowest Landau level. The longitudinal quark number susceptibility is found to increase with the temperature whereas the transverse one decreases with the temperature. We also compute the quark number susceptibility in the weak field approximation. We find that the thermomagnetic correction to the quark number susceptibility is very marginal in the weak field approximation.
