磁场作用下作为双凝聚体的威尔逊圈

Dressed Wilson loops as dual condensates in response to magnetic fields

Falk Bruckmann, Gergely Endrodi

摘要:

我们介绍了作为一种新的约束观测的穿着威尔逊圈。它由任意几何形状但面积固定的闭合平面环组成,其期望值随后者而衰减。修饰威尔逊圈的构造是基于手征凝聚体对磁场(和电场)的响应,从而将不同的物理概念联系起来。我们给出了动力学晶格组态上的广义凝聚和修饰威尔逊圈的结果,并证实了在大探测质量的限制下与传统的威尔逊圈的一致性。本文讨论了缀饰威尔逊圈的重整化。

英文摘要:

We introduce dressed Wilson loops as a novel confinement observable. It consists of closed planar loops of arbitrary geometry but fixed area and its expectation values decay with the latter. The construction of dressed Wilson loops is based on chiral condensates in response to magnetic (and electric) fields, thus linking different physical concepts. We present results for generalized condensates and dressed Wilson loops on dynamical lattice configurations and confirm the agreement with conventional Wilson loops in the limit of large probe mass. We comment on the renormalization of dressed Wilson loops.
