In this work, we investigate how the assumption of chemical equilibrium with leptons affects the deconfinement phase transition to quark matter. This is carried out within the framework of the Chiral Mean Field model allowing for nonzero net strangeness, corresponding to the conditions found in astrophysical scenarios. We build three‐dimensional quantum chromodynamics phase diagrams with temperature, baryon chemical potential, and either charge or isospin fraction or chemical potential to show how the deconfinement region collapses to a line in the special case of chemical equilibrium, such as the one established in the interior of cold catalyzed neutron stars.

化学平衡下的脱约束相变

在这项工作中，我们研究了具有轻子的化学平衡假设如何影响脱限相向夸克物质的转变。这是在手性平均场模型的框架内进行的，该模型允许非零净奇数，这与天体物理场景中的条件相对应。我们用温度，重子化学势以及电荷或同位旋比分数或化学势构建三维量子色动力学相图，以显示去约束区域如何在特殊的化学平衡情况下塌陷为一条线，例如在化学平衡中建立的一条线。内部的冷催化中子星。
