SU中心对称三维有效理论的格子模拟(2)Yang-Mills
Lattice simulation of a center symmetric three-dimensional effective theory for SU(2) Yang-Mills
摘要:
我们在三维空间中对SU(2)Wilson线的有效理论进行了模拟。我们的作用量包括动力学项、Wilson线的单圈微扰势、非微扰的“模糊袋”贡献和空间规范场。我们确定的理论的相图,并确认,在适度弱耦合,非微扰项导致本征值排斥在有限区域以上的退变相变。
英文摘要:
We perform simulations of an effective theory of SU(2) Wilson lines in three dimensions. Our action includes a kinetic term, the one-loop perturbative potential for the Wilson line, a non-perturbative "fuzzy-bag" contribution and spatial gauge fields. We determine the phase diagram of the theory and confirm that, at moderately weak coupling, the non-perturbative term leads to eigenvalue repulsion in a finite region above the deconfining phase transition.
