Pseudo-electromagnetic fields in 3D topological semimetals

R Ilan, AG Grushin, DI Pikulin - Nature Reviews Physics, 2020 - nature.com
Dirac and Weyl semimetals react to position-dependent and time-dependent perturbations,
such as strain, as if subject to emergent electromagnetic fields, known as pseudo-fields …

We investigate the response tensors in planar Hall (thermal Hall) configurations such that a
three-dimensional Weyl or multi-Weyl semimetal is subjected to the influence of an electric …

Mixed axial-torsional anomaly in Weyl semimetals

Y Ferreiros, Y Kedem, EJ Bergholtz, JH Bardarson - Physical review letters, 2019 - APS
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 …

Dislocation defect as a bulk probe of monopole charge of multi-Weyl semimetals

R Soto-Garrido, E Muñoz, V Juričić - Physical Review Research, 2020 - APS
Multi-Weyl semimetals feature band crossings with the dispersion that is, in general, linear in
only one direction, and as a consequence their band structure is characterized by the …

Acoustogalvanic effect in Dirac and Weyl semimetals

PO Sukhachov, H Rostami - Physical Review Letters, 2020 - APS
The acoustogalvanic effect is proposed as a nonlinear mechanism to generate a direct
