标题： Confinement-Higgs and deconfinement-Higgs transitions in four-dimensional SU(2) LGT at finite temperature

摘要： 我们通过数值模拟重新研究了(3+1)维SU(2)格点规范理论(LGT)在有限温度下规范场与希格斯场耦合的相结构。具体来说，我们探讨了两种不同的序参量，它们能够区分该理论的三个相：(i) Fredenhagen-Marcu算子用于区分去禁闭和禁闭/希格斯相；(ii) Green-site-Matsuyama重叠算子最近被提出用于区分禁闭和希格斯相。 显示英文摘要

摘要： We re-examine by numerical simulation the phase structure of the (3+1)-dimensional SU(2) lattice gauge theory (LGT) with gauge fields coupled to Higgs fields at finite temperature. Concretely, we explore two different order parameters which are able to distinguish the three phases of the theory: (i) the Fredenhagen-Marcu operator used to discriminate between deconfinement and confinement/Higgs phases and (ii) the Greensite-Matsuyama overlap operator proposed recently to distinguish confinement and Higgs phases.
