我们使用硬密圈微扰理论（HDLpt）计算了在同时存在夸克和同位旋化学势的情况下强磁化冷QCD物质的纵向压力和磁化强度。为此，我们首先在强磁场和同位旋密度存在的情况下得到了重整化的夸克和胶子传播子。我们发现压力随两种化学势单调增加。磁化强度为正，这表明冷夸克物质的顺磁性质。我们还讨论了由此产生的压力各向异性，在强场区域横向压力相对于纵向压力被抑制。
英文摘要
We have computed the longitudinal pressure and magnetization of strongly magnetized cold QCD matter in the presence of both quark and isospin chemical potentials using the hard-dense-loop perturbation theory (HDLpt). For that purpose, we have first obtained the resummed quark and gluon propagators in the presence of a strong magnetic field and isospin density. We have found that pressure gets monotonically enhanced with both chemical potentials. Magnetization is found to be positive, which indicates the paramagnetic nature of the cold quark matter. We also discuss the resulting pressure anisotropy, where the transverse pressure is suppressed relative to the longitudinal pressure in the strong-field regime.
