20 Jun 1995 | | Subject: | hep-th | | Affiliation: | Dipartimento di Fisica dell’Università and INFN Sezione di Lecce, Lecce, Italy | | Abstract: | We show that the classical non-abelian pure Chern-Simons action is related to nonrelativistic models in (2+1)-dimensions, via reductions of the gauge connection in Hermitian symmetric spaces. In such models the matter fields are coupled to gauge Chern-Simons fields, which are associated with the isotropy subgroup of the considered symmetric space. Moreover, they can be related to certain (integrable and non-integrable) evolution systems, as the Ishimori and the Heisenberg model. The main classical and quantum properties of these systems are discussed in connection with the topological field theory and the condensed matter physics. | | Source: | arXiv, hep-th/9506130 | | Services: | Forum | Review | PDF | Favorites | |
