Electromagnetic response of two interacting topological insulator spheres in external fields
J. Cornejo Gómez, M. Ibarra-Meneses, L. Medel Onofre +1
We study the static electromagnetic response of two spherical topological insulators embedded in a dielectric medium and subjected to a uniform external electric field. The gapped…

Exact modes, hybridization and polarization rotation of electromagnetic fields propagating in topological insulating slab
Sebastián Filipini, Mauro Cambiaso, Alberto Martín-Ruiz +1
We study electromagnetic waves in slab waveguides with a topological insulator core characterized by a topological magnetoelectric parameter (ME). TIs are electrically insulating i…
