标题： The non-Abelian dual Meissner effect as color-alignment in SU(2) lattice gauge theory

摘要： 通过广义的最大阿贝尔规范（MAG）提出了一种新的规范条件（m-规范）。 这种新规范允许残余U(1)在SU(2)规范群中的时空依赖性嵌入。 这种嵌入由一个色矢量$\vec{m}(x)$表征。 结果表明，这个矢量仅依赖于链接构型的规范不变部分。 我们的数值结果显示了空间时间中$\vec{m}(x)$场的颜色铁磁相关性。 关联长度趋于连续极限。 为了与MAG进行比较，我们引入了一类规范，它们在MAG和m-规范之间平滑过渡。 对于规范参数的广泛范围，真空分解为对齐矢量$\vec{m}$的区域。 在新的规范类别的背景下讨论了MAG的“中性粒子问题”。 显示英文摘要

摘要： A new gauge (m-gauge) condition is proposed by means of a generalization of the Maximal Abelian gauge (MAG). The new gauge admits a space time dependent embedding of the residual U(1) into the SU(2) gauge group. This embedding is characterized by a color vector $\vec{m}(x)$. It turns out that this vector only depends of gauge invariant parts of the link configurations. Our numerical results show color ferromagnetic correlations of the $\vec{m}(x)$ field in space-time. The correlation length scales towards the continuum limit. For comparison with the MAG, we introduce a class of gauges which smoothly interpolates between the MAG and the m-gauge. For a wide range of the gauge parameter, the vacuum decomposes into regions of aligned vectors $\vec{m}$. The ''neutral particle problem'' of MAG is addressed in the context of the new gauge class.
