论文摘要
我们研究了全息QCD模型中有限尺寸效应和边界条件的旋转下的不均匀性手性冷凝。 $ωR$确定的旋转抑制作用在不受边界条件影响的全息模型中得到了证实。对于中心的手性凝结,发现在Neumann边界条件下,有限的大小表现出两个相反的作用,即在高温下催化和低温下的反催化。相比之下,在差异边界条件下,有限尺寸对冷凝的影响是反催化,而小尺寸会导致从不均匀性到均相相的相变。对于不同的边界条件和尺寸,获得了QCD的温度角速度相图,发现临界温度随角速度降低。
We investigate inhomogeneous chiral condensation under rotation considering finite size effects and boundary conditions in the holographic QCD model. The rotational suppression effect determined by $Ωr$ is confirmed in the holographic model which is not influenced by the boundary conditions. For chiral condensation at the center, it is found that under Neumann boundary condition the finite size exhibits two opposite effects, i.e., catalysis at high temperatures and inverse catalysis at low temperatures. In contrast, under Dirichlet boundary condition, the effect of finite size on condensation is inverse catalysis, and small size induces a phase transition from inhomogeneous to homogeneous phase. The temperature-angular velocity phase diagrams of QCD are obtained for different boundary conditions and sizes, and it is found that the critical temperature decreases with angular velocity.
