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…
Diffusion in the presence of a chiral topological defect
Andy Manapany, Leila Moueddene, Bertrand Berche +1
We study the diffusion processes of a real scalar field in the presence of the distorsion field induced by a chiral topological defect. The defect modifies the usual Euclidean back…
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…
Thermal diode made by nematic liquid crystal
Djair Melo, Ivna Fernandes, Fernando Moraes +2
This work investigates how a thermal diode can be designed from a nematic liquid crystal confined inside a cylindrical capillary. In the case of homeotropic anchoring, a defect str…
