Geometrical optics limit of phonon transport in a channel of disclinations
Sébastien Fumeron, Bertrand Berche, Fernando Moraes +2
The presence of topological defects in a material can modify its electrical, acoustic or thermal properties. However, when a group of defects is present, the calculations can becom…
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…
