Giant, unconventional anomalous Hall effect in the metallic frustrated magnet candidate, KV 3 Sb 5
The anomalous Hall effect soars when Dirac quasiparticles meet frustrated magnetism.
Proposal to Detect Dark Matter using Axionic Topological Antiferromagnets
Antiferromagnetically doped topological insulators (A-TI) are among the candidates to host dynamical axion fields and axion-polaritons; weakly interacting quasiparticles that are analogous to the dark axion, a long sought after candidate dark matter particle. Here we demonstrate that using the axion quasiparticle antiferromagnetic resonance in A-TI's in conjunction with low-noise methods of detecting THz photons presents a viable route to detect axion dark matter with mass 0.7 to 3.5 meV, a range currently inaccessible to other dark matter detection experiments and proposals. The benefits of this method at high frequency are the tunability of the resonance with applied magnetic field, and t…
