Electromagnetic fields induced by an electric charge near a Weyl semimetal
A. Martín-Ruiz, M. Cambiaso, L. F. Urrutia
Weyl semimetals (WSM) are a new class of topological materials that exhibit a bulk Hall effect due to time-reversal symmetry breaking, as well as a chiral magnetic effect due to in…
The magnetoelectric coupling in Electrodynamics
A. Martín-Ruiz, M. Cambiaso, L. F. Urrutia
We explore a model akin to axion electrodynamics in which the axion field rather than being dynamical is a piecewise constant effective parameter encoding the…
Interaction of a hydrogenlike ion with a planar topological insulator
A. Martín-Ruiz, L. F. Urrutia
An electric charge near the surface of a topological insulator (TI) induces an image magnetic monopole. Here we study the spectra of hydrogenlike ions near the surface of a planar…
A Green's function approach to the Casimir effect on topological insulators with planar symmetry
A. Martín-Ruiz, M. Cambiaso, L. F. Urrutia
We investigate the Casimir stress on a topological insulator (TI) between two metallic plates. The TI is assumed to be joined to one of the plates and its surface in front of the o…
Jaynes-Cummings model in a finite Kerr medium
A. Martín Ruiz, Alejandro Frank, L. F. Urrutia
We introduce a spin model which exhibits the main properties of a Kerr medium to describe an intensity dependent coupling between a two-level atom and the radiation field. We selec…
