论文摘要
我们研究了螺旋物质的热力学，即夸克物质，其中净螺旋性（$ n_h $）处于平衡状态。相互作用是由具有两种夸克风味的重新归一化夸克 - 梅森模型建模的。螺旋密度是通过化学势$μ_H$在大型典型合奏形式主义中描述的。我们研究了从正常夸克物质和强子气体到螺旋物质的过渡，在零温度下绘制相图。我们研究了在有限温度下手性对称性的恢复，并表明净螺旋密度会柔和过渡，将临界端点移至较低的温度和更高的Baryon化学势。最后，我们简要讨论刚性旋转对螺旋物质的影响，尤其是对$ n_h $的波动，并证明这些旋转会增强。
We study the thermodynamics of helical matter, namely quark matter in which a net helicity, $n_H$, is in equilibrium. Interactions are modeled by the renormalized quark-meson model with two flavors of quarks. Helical density is described within the grand-canonical ensemble formalism via a chemical potential, $μ_H$. We study the transitions from the normal quark matter and hadron gas to the helical matter, drawing the phase diagram at zero temperature. We study the restoration of chiral symmetry at finite temperature and show that the net helical density softens the transition, moving the critical endpoint to lower temperature and higher baryon chemical potential. Finally, we discuss briefly the effect of a rigid rotation on the helical matter, in particular on the fluctuations of $n_H$, and show that these are enhanced by the rotation.
