摘要
应用独立元格试探作用量对3维SU(2)格点规范理论的相结构作了变分计算,所得内能曲线是光滑的,显示理论的禁闭性质。此计算改进了应用独立链试探作用量作变分累积展开方法所得的结果。
The phase structure of 3-dimensional 5U(2) lattice gauge theory is studied using variational method with an independent plaquette trial action. The mean-plaquette internal energy E_p～β curve is smooth, which shows only one confining phase, and is better than that given by independent link trial action.
