Parity Anomaly in the non-linear response of Nodal-Line Semimetals
Alberto Martín-Ruiz, Alberto Cortijo
Nodal-line semimetals are topological semimetals characterized by one-dimensional band-touching loops protected by the combined symmetry of inversion and time-reversa…
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…
Magnetoelectric effect in cylindrical topological insulators
A. Martín-Ruiz
Topological insulators (TIs) exhibit a quantized magnetoelectric response when time-reversal symmetry is broken on its surface. This unusual electromagnetic (EM) response is a uniq…
Testing Lorentz- and CPT-invariance with ultracold neutrons
A. Martín-Ruiz, C. A. Escobar
In this paper we investigate, within the standard model extension framework, the influence of Lorentz- and CPT-violating terms on gravitational quantum states of ultracold neutrons…
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…
