We investigate the existence of inhomogeneous chiral phases in the quark-meson model with explicit chiral-symmetry breaking. We find that the inhomogeneous region shrinks with increasing pion masses but survives for the physical value of m_π. The instability towards inhomogeneous matter occurs in the scalar channel, while pseudoscalar modes are disfavored.

夸克-介子模型中具有明显手性对称破坏的不均匀相

我们调查了夸克-介子模型中具有明显的手性对称破坏的不均匀手性相的存在。我们发现，随着介子群众，但存活的体力值不均匀区域收缩米_π。对不均匀物质的不稳定性发生在标量通道中，而伪标量模式则不受欢迎。
