Topological Fermi-liquid theory for interacting Weyl metals with time reversal symmetry breaking

YS Jho, JH Han, KS Kim - Physical Review B, 2017 - APS
Introducing both the Berry curvature and the chiral anomaly into Landau's Fermi-liquid
theory, we construct a topological Fermi-liquid theory, applicable to interacting Weyl metals …

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 …

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 …

Emergence of non-Fermi-liquid type Weyl metals driven by doped magnetic impurities in spin-orbit coupled semiconductors

Constructing an effective field theory in terms of doped magnetic impurities [described by an
O (3) vector model with a random mass term], itinerant electrons of spin-orbit coupled …

Anomalous Hall effect in Weyl semimetal

D Shin, J Kim, DF Weickert - public.magnet.fsu.edu
Weyl metals have exotic transport phenomena owing to chiral anomaly. One of these is
negative longitudinal magneto resistance which have been reported several. Beyond the …
