摘要
用鞍点平均场方法(到单圈修正)和强耦合展开技术,研究了非各向同性耦合Z(2)格点规范模型的相结构。结果表明,对D=4,d=D-1=3情形层相存在。并按不取规范与取轴规范两种情况进行了计算。
An unisotropic Z(2) lattice gauge model was studied by using the mean field method (with one-loop correction) and strong-coupling expansion technique. In the case of dimension D =4 and d=D-1=3, we found that the layer phase exists. The calculation was performed with and without gauge fixing.
