论文摘要
我们研究了在旋转下有限的巴属化学电位下,在三种味道QCD中研究低密度辐射物质和高密度颜色锁定的颜色超导阶段的基态。我们发现,在两种情况下,在足够快速的旋转下,ETA'Meson和QCD异常的旋转诱导的拓扑项的组合都会导致ETA'Meson的不均匀冷凝物,称为手性Soliton Lattice(CSL)。我们发现,当巴属化学势比Isospin化学电位大得多时,实现ETA'CSL的临界角速度远小于以前发现的PI_0 CSL。我们还认为,在旋转的情况下,应连续连接在低密度和高密度的口味对称QCD中的ETA'CSL状态,从而扩展夸克 - 哈德隆连续性的猜想。
We study the ground states of low-density hadronic matter and high-density color-flavor locked color superconducting phase in three-flavor QCD at finite baryon chemical potential under rotation. We find that, in both cases under sufficiently fast rotation, the combination of the rotation-induced topological term for the eta' meson and the QCD anomaly leads to an inhomogeneous condensate of the eta' meson, known as the chiral soliton lattice (CSL). We find that, when baryon chemical potential is much larger than isospin chemical potential, the critical angular velocity for the realization of the eta' CSL is much smaller than that for the pi_0 CSL found previously. We also argue that the eta' CSL states in flavor-symmetric QCD at low density and high density should be continuously connected, extending the quark-hadron continuity conjecture in the presence of the rotation.
