✦ Synopsis

We proposed an 'Ichimatsu'-decomposed lattice gauge theory with fermionic symmetries.

The vacuum structures of the gauge sector with two coupling constants (&,,&) are investigated for 3-dimensional Zz and 4dimensional SU(2) cases using mean-field approximation and numerical simulation.

We found two phases on the (/?,, PC) phase diagram for 3-dim. Z2 case, while the diagram is a single phase for the latter.
