I accomplished two studies on the topological phases of low-energy dense QCD.The first was a magnetized Skyrmion system describing the hadron properties altered by an external magnetic field. Our results hint at the enhancement of the baryonic confinement induced by the magnetic field, in an original approach.The second was a further investigation of a competing mesonic phase (against baryonic phase) under a strong magnetic field, namely the chiral soliton lattice. We innovatively encompass the eta meson into the chiral perturbation theory which was usually in terms of only pions. We found the ground state given such a U(2) field is a mixed soliton lattice or quasicrystal with nontrivial windings of both neutral pion and eta, which could be the first incarnation of a quasicrystal in QCD.

我完成了两项关于低能密度QCD拓扑阶段的研究。第一个是一个磁化的天空系统，描述了外部磁场改变的强子特性。我们的结果暗示，在原始方法中，磁场诱导的重型限制的增强。第二，在强磁场下进一步研究了竞争性的中性相（针对重男性相），即手性索尼顿晶格。我们将Eta Meson纳入了手性扰动理论，通常仅在普力上。我们发现，鉴于这种U（2）场的基态是中性锥子和ETA的非平凡绕组的混合孤子晶格或准晶体，这可能是QCD中准晶体的第一个化身。
