We present a theory of the intrinsic anomalous Hall effect in a model of a doped Weyl semimetal, which serves here as the simplest toy model of a generic three-dimensional metallic ferromagnet with Weyl nodes in the electronic structure. We analytically evaluate the anomalous Hall conductivity as a function of doping, which allows us to explicitly separate the Fermi surface and non Fermi surface contributions to the Hall conductivity by carefully evaluating the zero frequency and zero…

TLDR
The AHE in a Weyl metal is shown to be a purely intrinsic, universal property, fully determined by the location of the Weyl nodes in the first Brillouin zone.
Anomalous Hall effect in Weyl superconductors
We present a theory of the anomalous Hall effect in a topological Weyl superconductor with broken time reversal symmetry. Specifically, we consider a ferromagnetic Weyl metal with two Weyl nodes of
Universal charge and current on magnetic domain walls in Weyl semimetals
Domain walls in three-dimensional Weyl semimetals, formed by localized magnetic moments, are investigated. There appear bound states around the domain wall with the discrete spectrum, among which we

TLDR
The AHE in a Weyl metal is shown to be a purely intrinsic, universal property, fully determined by the location of the Weyl nodes in the first Brillouin zone, and a fully microscopic theory of diffusive magnetotransport in Weyl metals is developed.
Quantum anomalous Hall effect and related topological electronic states
Over a long period of exploration, the successful observation of quantized version of anomalous Hall effect (AHE) in thin film of magnetically doped topological insulator (TI) completed a quantum

TLDR
An ultra-thin film of topological insulator (TI) multilayer is investigated as a model for a three-dimensional (3D) Weyl semimetal and the chiral magnetic effect of the system in the presence of a time dependent magnetic field is studied.
Charge Pumping Induced by Magnetic Texture Dynamics in Weyl Semimetals
Spin-momentum locking in Weyl semimetals correlates the orbital motion of electrons with background magnetic textures. We show here that the dynamics of a magnetic texture in a magnetic Weyl
Magnetic Textures and Dynamics in Magnetic Weyl Semimetals
Recent theoretical and experimental attemps have been successful in finding magnetic Weyl semimetal phases, which show both nodal-point structure in the electronic bands and magnetic orders. Beyond
Intrinsic Torques Emerging from Anomalous Velocity in Magnetic Textures
Momentum-space topology of electrons under strong spin-orbit coupling contributes to the electrically induced torques exerting on magnetic textures insensitively to disorder or thermal fluctuation.
