作为光学介质的杨-米尔斯场

Yang-Mills fields as optical media

R. Aldrovandi, A. L. Barbosa

摘要:

杨-米尔斯场的几何化,SU(2)规范理论成为等价的3空间几何-或光学系统-检查。在第一步,周围的空间仍然是欧几里德和当前的问题,平坦的空间可以从一个新的角度来看。例如,吴杨歧义似乎与不同的度量保持联系的多种可能的扭曲有关。在第二步骤中,周围空间也变得弯曲。一般来说,严格黎曼的度量扇区扮演着任意宿主空间的角色,规范场由扭曲表示。然而,对于某些字段配置,可以获得纯度量表示。在这些情况下,如果空间是对称齐次的,则Christoffel联络自动是杨-米尔斯方程的解。

英文摘要:

A geometrization of the Yang-Mills field, by which an SU(2) gauge theory becomes equivalent to a 3-space geometry - or optical system - is examined. In a first step, ambient space remains Euclidean and current problems on flat space can be looked at from a new point of view. The Wu-Yang ambiguity, for example, appears related to the multiple possible torsions of distinct metric-preserving connections. In a second step, also the ambient space becomes curved. In general, the strictly Riemannian, metric sector plays the role of an arbitrary host space, with the gauge field represented by a contorsion. For some field configurations, however, it is possible to obtain a purely metric representation. In those cases, if the space is symmetric homogeneous the Christoffel connections are automatically solutions of the Yang-Mills equations.
