Theory of phonon instabilities in Weyl semimetals at high magnetic fields
Sarbajaya Kundu, Claude Bourbonnais, Ion Garate
The behavior of three-dimensional (3D) semimetals under strong magnetic fields is a topic of recurring interest in condensed matter physics. Recently, the advent of Weyl and Dirac…
Phonon helicity induced by electronic Berry curvature in Dirac materials
Lun-Hui Hu, Jiabin Yu, Ion Garate +1
In two-dimensional insulators with time-reversal (TR) symmetry, a nonzero local Berry curvature of low-energy massive Dirac fermions can give rise to nontrivial spin and charge res…
From Topological Superconductivity to Quantum Hall States in Coupled Wires
Fan Yang, Vivien Perrin, Alexandru Petrescu +2
We present a theoretical study of the interplay between topological p-wave superconductivity, orbital magnetic fields and quantum Hall phases in coupled wire systems. First, we cal…
Signatures of the chiral anomaly in phonon dynamics
Pierre Rinkel, Pedro L. S. Lopes, Ion Garate
Discovered in high-energy physics, the chiral anomaly has recently made way to materials science by virtue of Weyl semimetals (WSM). Thus far, the main efforts to probe the chiral…
Detecting band inversions by measuring the environment: fingerprints of electronic band topology in bulk phonon linewidths
Kush Saha, Katherine Légaré, Ion Garate
The interplay between topological phases of matter and dissipative baths constitutes an emergent research topic with links to condensed matter, photonic crystals, cold atomic gases…
Surface-to-bulk scattering in topological insulator films
Kush Saha, Ion Garate
We present a quantitative microscopic theory of the disorder- and phonon-induced coupling between surface and bulk states in topological insulator (TI) films. We find a simple stru…
