论文摘要
我们建议使用正交SO(3)-matrix对三维$ n $ field的量规参数化,而该字段依次通过在Lie代数SO(3)(3)(旋转 - 角度字段)中的字段定义。旋转角域具有额外的自由度,这对应于$ n $ field周围的旋转自由度。结果,我们获得了带有局部SO(2)= U(1)对称性的量规模型,该对称性不包含U(1)量规场。
We propose gauge parameterization of the three-dimensional $n$-field using orthogonal SO(3)-matrix which, in turn, is defined by a field taking values in the Lie algebra so(3) (rotational-angle field). The rotational-angle field has an additional degree of freedom, which corresponds to the gauge degree of freedom of rotations around the $n$-field. As a result, we obtain a gauge model with local SO(2)=U(1) symmetry that does not contain a U(1) gauge field.
