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…
From isospin generators to BRST quantization of higher spin massless fields
J. Alfaro, M. Cambiaso
Motivated by construction of isospin generators in particle physics (built form the SU(2) algebra), we find an equivalence between the algebra of these generators and those of the…
On the consistency of Lorentz invariance violation in QED induced by fermions in constant axial-vector background
J. Alfaro, A. A. Andrianov, M. Cambiaso +2
We show for the first time that the induced parity--even Lorentz invariance violation can be unambiguously calculated in the physically justified and minimally broken dimensional r…
