论文摘要
我们考虑了系统状态方程中均匀的磁场产生的各向异性,在存在磁场的情况下,在存在磁场的情况下以有限密度的形式研究了强子Quark相变。我们找到了一种新的各向异性平衡条件,该条件将沿两个阶段之间的边界驱动一阶相变。固定磁场在辐射相中,通过在零温度下增加男性化学电位来实现相变。结果表明,在系统从辐射式转变为夸克相后,磁场会轻微增强。两个相之间的磁场不连续性由磁单孔的表面密度支撑,磁性单极的表面密度在分隔两个相的边界处积聚。讨论了负责单极电荷密度生成的机制。在夸克相中,发现每个相具有较高的磁敏感性。在纸上突出显示了与中子恒星物理的联系。
We investigate the hadron-quark phase transition at finite density in the presence of a magnetic field taking into account the anisotropy created by a uniform magnetic field in the system's equations of state. We find a new anisotropic equilibrium condition that will drive the first-order phase transition along the boundary between the two phases. Fixing the magnetic field in the hadronic phase, the phase transition is realized by increasing the baryonic chemical potential at zero temperature. It is shown that the magnetic field is mildly boosted after the system transitions from the hadronic to the quark phase. The magnetic-field discontinuity between the two phases is supported by a surface density of magnetic monopoles, which accumulate at the boundary separating the two phases. The mechanism responsible for the monopole charge density generation is discussed. Each phase is found to be paramagnetic with higher magnetic susceptibility in the quark phase. The connection with the physics of neutron stars is highlighted through out the paper.
