费米子畴壁斯格明子在磁场下的两味手征微扰理论的手征孤子晶格中作为基态出现，与量子色动力学基础理论中的重子相关联。我们分析畴壁斯格明子的电磁屏蔽特性，该特性可用于理解重子密度在磁场和化学势相图上的分布。在零温度下，利用模有效理论发现，斯格明子密度在垂直于磁场的手征孤子晶格圆盘上，直至费米动量时达到饱和。我们进一步研究耦合量子电动力学的手征微扰理论，该理论可产生有限温度屏蔽，其中通过组合德拜质量/长度预测出静态费米子畴壁斯格明子的屏蔽效应。
英文摘要
Fermionic domain-wall Skyrmions arise in the chiral soliton lattice of two flavor chiral perturbation theory in a magnetic field as the ground state and are associated with baryons of the underlying theory of quantum chromodynamics. We analyze the electromagnetic screening characteristics of domain-wall Skyrmions that give insight into baryon density on the magnetic field and chemical potential phase diagram. At zero temperature, using the moduli effective theory, it is found Skyrmion density is saturated up to the Fermi momenta on the disk of the chiral soliton lattice orthogonal to the magnetic field. We further study chiral perturbation theory coupled to quantum electrodynamics leading to finite temperature screening, wherein a static fermionic domain-wall Skyrmion screening is predicted through a combined Debye mass/length.
