标题： Quark confinement and gauge invariant monopoles in SU(2) YM

摘要： 我们简要回顾了最近在非线性变量变换的新格点公式方面获得的结果，该公式曾被称为SU(2)杨-米尔斯理论中的Cho-Faddeev-Niemi分解。 基于此公式，我们提出了一种新的规范不变的磁单极电流定义，该定义保证了磁荷的量子化。 我们还证明了在格点SU(2)杨-米尔斯理论中，磁单极子对弦张力的主导作用。 我们的公式使得能够以规范不变的方式再现迄今为止仅在最大阿贝尔规范中获得的显著结果。 显示英文摘要

摘要： We give a short review of recently obtained results on a new lattice formulation of the non-linear change of variables which was once called the Cho--Faddeev--Niemi decomposition in SU(2) Yang-Mills theory. Based on this formulation, we proposed a new gauge-invariant definition of the magnetic monopole current which guarantees the magnetic charge quantization. We also demonstrated the magnetic monopole dominance in the string tension in SU(2) Yang-Mills theory on a lattice. Our formulation enables one to reproduce in the gauge-invariant way remarkable results obtained so far only in the Maximally Abelian gauge.
