威尔逊圈的一个线性方程

A Linear Equation for Wilson Loops

Poul Olesen

摘要:

的Maxiko-Migdal回路方程是非线性的,在面积导数的一阶,但我们表明,在QCD $_2$简单的回路,它是可能的,重新制定这个方程作为一个线性方程的二阶导数。该方程是一个具有三维库仑势的束缚态薛定谔方程。因此,环路动力学导致了一个令人惊讶的新的图片的限制,这种现象是由于(绑定状态)在环路空间的本地化,与威尔逊圈的特征半径以外的指数衰减。

英文摘要:

The Makeenko-Migdal loop equation is non-linear and first order in the area derivative, but we show that for simple loops in QCD$_2$ it is possible to reformulate this equation as a linear equation with second order derivatives. This equation is a bound state Schrödinger equation with a three dimensional Coulomb potential. Thus, loop dynamics leads to a surprising new picture of confinement, where this phenomenon is due to a (bound state) localization in loop space, with the Wilson loops decaying exponentially outside a characteristic radius.
