Violation of Ohm's law in a Weyl metal

D Shin, Y Lee, M Sasaki, YH Jeong, F Weickert… - Nature materials, 2017 - nature.com
Ohm's law is a fundamental paradigm in the electrical transport of metals. Any transport
signatures violating Ohm's law would give an indisputable fingerprint for a novel metallic …

Large violation of the Wiedemann–Franz law in Heusler, ferromagnetic, Weyl semimetal Co2MnAl

RA Robinson, L Min, SH Lee, P Li… - Journal of Physics D …, 2021 - iopscience.iop.org
Abstract The Wiedemann–Franz (WF) law relates the electronic component of the thermal

Chiral pair of Fermi arcs, anomaly cancellation, and spin or valley Hall effects in Weyl metals with broken inversion symmetry

I Jang, KS Kim - Physical Review B, 2018 - APS
Anomaly cancellation has been shown to occur in broken time-reversal symmetry Weyl
metals, which explains the existence of a Fermi arc. We extend this result in the case of …

Transmission and reflection coefficients and Faraday/Kerr rotations as a function of applied magnetic fields in spin-orbit coupled Dirac metals

J Yang, J Kim, KS Kim - Physical Review B, 2018 - APS
We reveal the nature of propagation and reflection of light in spin-orbit coupled Dirac metals
under external magnetic fields. Such applied magnetic fields split the fourfold degeneracy of …

Interplay between chiral magnetic and Kondo effects in Weyl metal phase

KS Kim, JH Han - Current Applied Physics, 2019 - Elsevier
We investigate the Kondo effect in a Weyl metal state, which occurs from a spin-orbit
coupled Dirac metal phase under magnetic fields. We start from an effective field theory in …

Anomalous plasmon mode in strained Weyl semimetals

S Heidari, D Culcer, R Asgari - Physical Review B, 2021 - APS
An exotic anomalous plasmon (AP) mode is found in strained Weyl semimetals utilizing the
topological Landau Fermi liquid and chiral kinetic theories, in which quasiparticle …

Nonlocal transport phenomena in Weyl metals beyond the mesoscopic scale

J Yang, KS Kim - Physical Review B, 2021 - APS
Axion electrodynamics governs electromagnetic properties of Weyl metals. Although
transmission and reflection measurements of light have been proposed to confirm the axion …

Collective dynamics of Fermi surface fluctuations in an interacting Weyl metal phase

C Jeong, KS Kim - Physical Review B, 2018 - APS
Instabilities in a Landau's Fermi-liquid state occur, increasing the strength of interaction
parameters in the Landau's Fermi-liquid theory. Introducing both the Berry curvature and …
