摘要
本文运用累积展开方法对禁闭的(2+1)维U(1)规范理论进行研究。给出了有限温度下它所发生的解除禁闭的相变,所得相变点位置和Monte carlo结果基本符合。
In this paper,as a complement of Ref[4],the(2+1)-dimensional U(1)lattice gauge theory at finitetemperature is studied in the variational cumulant expansion approach.The deconfinement transition forthis theory is obtained.The comparison with Monte Carlo result is also presented.
