关于解除禁闭相变附近通量管厚度的线性增加

On the linear increase of the flux tube thickness near the deconfinement transition

A. Allais, M. Caselle

摘要:

研究了一般格点规范理论在退细化相变附近的通量管厚度。众所周知,有效弦模型预测,在零温度下,对于任何限制的LGT,通量管厚度都是夸克间距离的函数。也许不太为人所知的是,这个模型预测了在解除禁闭转变附近的线性增加。我们提出了一个精确的推导这个结果,并将其与一组高精度的模拟的情况下的三维规范伊辛模型。

英文摘要:

We study the flux tube thickness of a generic Lattice Gauge Theory near the deconfining phase transition. It is well known that the effective string model predicts a logarithmic increase of the flux tube thickness as a function of the interquark distance for any confining LGT at zero temperature. It is perhaps less known that this same model predicts a linear increase in the vicinity of the deconfinement transition. We present a precise derivation of this result and compare it with a set of high precision simulations in the case of the 3d gauge Ising model.
