通过使用强耦合方法,可以计算长磁通串的能量,并使用该量对理论进行重整化。这给出了重正化群 beta 函数的扩展,它可以从强耦合极限平滑地外推到渐近自由值。该理论由该范围内三个性质不同的区域来描述。
With use of strong-coupling methods, the energy of a long flux string is computed and this quantity is used to renormalize the theory. This gives an expansion for the renormalization-group beta function which smoothly extrapolates from the strong-coupling limit to the asymptotic-freedom value. The theory is described by three qualitatively distinct regions over this range.
