An Abelian Higgs model for disclinations in nematics
A. de Pádua Santos, F. Moraes, F. A. N. Santos +1
Topological defects in elastic media may be described by a geometric field akin to three-dimensional gravity. From this point of view, disclinations are line defects of zero width…
A simple light-trapping device from a hyperbolic metamaterial on a catenoid
Frankbelson dos Santos Azevedo, José Diêgo M. de Lima, Antônio de Pádua Santos +2
By using both ray and wave optics, we show that a simple device which consists on a film of hyperbolic metamaterial on the surface of a catenoid can be used to trap light. From the…
Gravitating non-Abelian cosmic strings
Antônio de Pádua Santos, Eugênio R. Bezerra de Mello
In this paper we study regular cosmic string solutions of the non-Abelian Higgs model coupled with the Einstein gravity. In order to do that, we constructed a set of coupled differ…
