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…
Geometric theory of topological defects: methodological developments and new trends
Sébastien Fumeron, Bertrand Berche, Fernando Moraes
Liquid crystals generally support orientational singularities of the director field known as topological defects. These latter modifiy transport properties in their vicinity as if…
Introduction to topological defects: from liquid crystals to particle physics
Sébastien Fumeron, Bertrand Berche
Liquid crystals are assemblies of rod-like molecules which self-organize to form mesophases, in-between ordinary liquids and anisotropic crystals. At each point, the molecules coll…
Principles of thermal design with nematic liquid crystals
S. Fumeron, E. Pereira, F. Moraes
Highly engineered materials are arousing great interest because of their ability to manipulate heat, as described by coordinate transformation approach. Based on the recently devel…
Retrieving the saddle-splay elastic constant of nematic liquid crystals from an algebraic approach
Sébastien Fumeron, Fernando Moraes, Erms Pereira
The physics of light interference experiments is well established for nematic liquid crystals. Using well-known techniques, it is possible to obtain important quantities, such as t…
Generation of optical vorticity from topological defects
Sébastien Fumeron, Erms Pereira, Fernando Moraes
The propagation of an electromagnetic wave in a medium with a screw dislocation is studied. Adopting the formalism of differential forms, it is shown that torsion is responsible fo…
