本文研究了中子星核中存在两种非均匀相的可能性：一种是库仑晶体，即夸克-强子面结构;另一种是手征晶体。在库仑晶体中，非均匀相的出现是表面张力和库仑相互作用平衡的结果。在手征晶体中，我们研究了具有空间调制的非均匀手征凝聚体。在1+1维的简单模型中，这种凝聚态具有与凝聚态物理中熟知的FFLO态相同的特征。
We study the possibility of two types of inhomogeneous phases in core of neutron stars: one is the Coulomb crystal, which is known as quark-hadron pasta structures, and another one is chiral crystal. In the Coulomb crystal, the inhomogeneous phase appears as the result of the balance between the surface tension and the Coulomb interaction. In chiral crystal, we study the inhomogeneous chiral condensate, which has spatial modulation. In the simple model in 1+1 dimensions, this condensate has the same feature with the FFLO state, which is well known in the condensed matter physics.
