Yang-Mills fields as optical media | | R. Aldrovandi

27 Jul 2001 | | Journal: | Int. J. Theor. Phys. 39 (2000) 1085 | | Subject: | Mathematical Physics | math-ph hep-th math.MP | | Abstract: | 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. | | Source: | arXiv, math-ph/0107027 | | Services: | Forum | Review | PDF | Favorites | |
