SU有效理论中的本征值排斥(2)三维Wilson线

Eigenvalue repulsion in an effective theory of SU(2) Wilson lines in three dimensions

Adrian Dumitru, Dominik Smith

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。我们包括一个非微扰的“模糊袋”的贡献,这是添加到一个循环的威尔逊线微扰潜力。我们确认,在适度弱耦合,这导致特征值排斥在有限区域以上的退变相变收缩的极端弱耦合限制。一个非平凡的Z(N)对称真空出现在受限相。

英文摘要:

We perform simulations of an effective theory of SU(2) Wilson lines in three dimensions. We include a non-perturbative "fuzzy-bag" contribution which is added to the one-loop perturbative potential for the Wilson line. We confirm that, at moderately weak coupling, this leads to eigenvalue repulsion in a finite region above the deconfining phase transition which shrinks in the extreme weak-coupling limit. A non-trivial Z(N) symmetric vacuum arises in the confined phase.
