标题： Vacuum Structure of the Ichimatsu-Decomposed Lattice Models

摘要： 我们提出了一种具有费米对称性的“Ichimatsu”分解格点规范理论。 通过平均场近似和数值模拟，研究了具有两个耦合常数（$\beta_p,\beta_c$）的规范部分在三维 Z$_2$和四维 SU(2) 情况下的真空结构。 我们发现对于三维 Z$_2$情况，在（$\beta_p,\beta_c$）相图上存在两个相，而后者相图则是一个相。 显示英文摘要

摘要： We proposed an `Ichimatsu'-decomposed lattice gauge theory with fermionic symmetries. The vacuum structures of the gauge sector with two coupling constants ($\beta_p,\beta_c$) are investigated for 3-dimensional Z$_2$ and 4-dimensional SU(2) cases using mean-field approximation and numerical simulation. We found two phases on the ($\beta_p,\beta_c$) phase diagram for 3-dim. Z$_2$ case, while the diagram is a single phase for the latter.
