Experimental demonstration of a magnetically induced warping transition in a topological insulator mediated by rare-earth surface dopants
Beatriz Muñiz Cano, Yago Ferreiros, Pierre A. Pantaleón +12
Magnetic topological insulators (MTI) constitute a novel class of materials where the topologically protected band structure coexists with long-range ferromagnetic order, which can…
Thermal transport, geometry, and anomalies
Maxim N. Chernodub, Yago Ferreiros, Adolfo G. Grushin +2
The relation between thermal transport and gravity was highlighted in the seminal work by Luttinger in 1964, and has been extensively developed to understand thermal transport, mos…
Electric manipulation of domain walls in magnetic Weyl semimetals via the axial anomaly
Julia D. Hannukainen, Alberto Cortijo, Jens H. Bardarson +1
We show how the axial (chiral) anomaly induces a spin torque on the magnetization in magnetic Weyl semimetals. The anomaly produces an imbalance in left- and right-handed chirality…
On chiral responses to geometric torsion
Yago Ferreiros, Karl Landsteiner
We show that geometric torsion does not lead to new chiral dissipationless transport effects. Instead apparent response to torsion can be viewed as a manifestation of the chiral vo…
Axial anomaly generation by domain wall motion in Weyl semimetals
Julia D. Hannukainen, Yago Ferreiros, Alberto Cortijo +1
A space-time dependent node separation in Weyl semimetals acts as an axial vector field. Coupled with domain wall motion in magnetic Weyl semimetals, this induces axial electric an…
Mixed axial-torsional anomaly in Weyl semimetals
Yago Ferreiros, Yaron Kedem, Emil J. Bergholtz +1
We show that Weyl semimetals exhibit a mixed axial-torsional anomaly in the presence of axial torsion, a concept exclusive of these materials with no known natural fundamental inte…
Boson-fermion duality in a gravitational background
Yago Ferreiros, Eduardo Fradkin
We study the dimensional boson-fermion duality in the presence of background curvature and electromagnetic fields. The main players are, on the one hand, a massive complex $|…
Anisotropic fixed points in Dirac and Weyl semimetals
Oscar Pozo, Yago Ferreiros, María A. H. Vozmediano
The effective low energy description of interacting Dirac and Weyl semimetals is that of massless quantum electrodynamics with several Lorentz breaking material parameters. We perf…
Elastic Gauge Fields and Hall Viscosity of Dirac Magnons
Yago Ferreiros, María A. H. Vozmediano
We analyze the coupling of elastic lattice deformations to the magnon degrees of freedom of magnon Dirac materials. For a Honeycomb ferromagnet we find that, as it happens in the c…
Anomalous Nernst and Thermal Hall Effects in Tilted Weyl Semimetals
Yago Ferreiros, A. A. Zyuzin, Jens H. Bardarson
We study the anomalous Nernst and thermal Hall effects in a linearized low-energy model of a tilted Weyl semimetal, with two Weyl nodes separated in momentum space. For inversion s…
Elastic Gauge Fields in Weyl Semimetals
Alberto Cortijo, Yago Ferreiros, Karl Landsteiner +1
We show that, as it happens in graphene, elastic deformations couple to the electronic degrees of freedom as pseudo gauge fields in Weyl semimetals. We derive the form of the elast…
Unconventional electromagnetic mode in neutral Weyl Semimetals
Yago Ferreiros, Alberto Cortijo
We study light propagation in a neutral Weyl semimetal with the Fermi level lying at the Weyl nodes in the weak self-interacting regime. The nontrivial topology induces a screening…
Dirac electrons and domain walls: a realization in junctions of ferromagnets and topological insulators
Yago Ferreiros, F. J. Buijnsters, M. I. Katsnelson
We study a system of Dirac electrons with finite density of charge carriers coupled to an external electromagnetic field in two spatial dimensions, with a domain wall (DW) mass ter…
Large conduction band and Fermi velocity spin splittings due to Coulomb interactions in single-layer MoS_{2}
Yago Ferreiros, Alberto Cortijo
We study the effect of Coulomb interactions on the low energy band structure of single-layer transition metal dichalcogenide semiconductors using an effective low energy model. We…
Domain Wall Motion in Thin-Film Magnets/ Topological Insulator Junctions
Yago Ferreiros, Alberto Cortijo
We derive the equations of motion of a Domain Wall in a thin-film magnet coupled to the surface states of a Topological Insulator in the presence of of both an electric field along…
