SEMILOCAL NONTOPOLOGICAL SOLITONS IN A CHERN-SIMONS THEORY. | | Manuel Torres
; | | Date: |
12 Dec 1994 | | Journal: | Phys.Rev. D51 (1995) 4533-4542 | | Subject: | hep-th | | Abstract: | We show the existence of self-dual semilocal nontopological vortices in a $Phi^2$ Chern-Simons (C-S) theory. The model of scalar and gauge fields with a $SU(2)_{global} imes U(1)_{local}$ symmetry includes both the C-S term and an anomalous magnetic contribution. It is demonstrated here, that the vortices are stable or unstable according to whether the vector topological mass $kappa$ is less than or greater than the mass $m$ of the scalar field. At the boundary, $kappa = m$, there is a two-parameter family of solutions all saturating the self-dual limit. The vortex solutions continuously interpolates between a ring shaped structure and a flux tube configuration. | | Source: | arXiv, hep-th/9501041 | | Services: | Forum | Review | PDF | Favorites | |
