Ferromagnetic Weyl semi-metals exhibit an anomalous Hall effect, a consequence of their topological properties. In the non-interacting case, the derivative of the orbital magnetization with respect to chemical potential is proportional to this anomalous Hall effect, the Str$\check{\text{e}}$da formula. Motivated by compounds such as $\text{Mn}_3\text{Sn}$, here we investigate how interactions modeled by a Hubbard $U$ impact on both quantities when the Fermi energy is either aligned with the…

Interaction and temperature effects on the magneto-optical conductivity of Weyl liquids
Negative magnetoresistance is one of the manifestations of the chiral anomaly in Weyl semimetals. The magneto-optical conductivity also shows transitions between Landau levels that are not spaced as
Berry curvature, orbital magnetization, and Nernst effect in biased bilayer WSe2
A valley-contrasting Berry curvature in bilayer transition metal dichalcogenides with spin-orbit coupling can generate valley magnetization when the inversion symmetry is broken, for example, by an
Fate of Fermi-arc states in gapped Weyl semimetals under long-range interactions
For noninteracting Weyl semimetals (WSMs), Fermi-arc surface states can arise when there exist gapless Weyl nodes in the bulk single-particle spectrum. However, in the presence of electronic
Numerical study of disorder on the orbital magnetization in two dimensions.
This manuscript performs a numerical study on the fate of the OM under disorder, by using this method on the Haldane model in two dimensions, which can be tuned between a normal insulator or a Chern insulator at half filling.
Dynamical correlation enhanced orbital magnetization in VI3
The effect of electronic correlations on the orbital magnetization in real materials has not been explored beyond a static mean-field level. Based on the dynamical mean-field theory, the effect of
Quasiparticle Properties under Interactions in Weyl and Nodal Line Semimetals
It is argued that the nontrivial evolution of Weyl points and nodal lines under interaction is due to the presence of symmetry breaking order, e.g., a ferromagnetic moment, in the framework of mean field theory, whereas the stability of Wey points under interactions is protected by symmetry.

Current-induced orbital magnetization in systems without inversion symmetry
In systems with time-reversal symmetry, the orbital magnetization is zero in equilibrium. Recently, it has been proposed that the orbital magnetization can be induced by an electric current in a

In the present study, zero field splitting (ZFS) parameters are investigated for Mn(II) ion doped perovskites, viz. PbTiO3, BaTiO3 and SrTiO3. The ZFS parameter and magnetisation induced in the host


Evidence for magnetic Weyl fermions in a correlated metal.
Experimental evidence is reported for magnetic Weyl fermions in Mn3Sn, a non-collinear antiferromagnet that exhibits a large anomalous Hall effect, even at room temperature, and lays the foundation for a new field of science and technology involving the magnetic Wey excitations of strongly correlated electron systems such as Mn3 Sn.

Spin-orbit coupling introduces chirality into electronic structure. This can have profound effects on the magnetization induced by orbital motion of electrons. Here we derive a formula for the

Interacting Weyl semimetals: characterization via the topological Hamiltonian and its breakdown.
This work derives a simple criterion to identify and characterize WSMs in an interacting setting using the exact electronic Green's function at zero frequency, which defines a topological Bloch Hamiltonian and introduces a WSM-like phase for which this criterion breaks down due to fractionalization.
Anomalous Hall effect in Weyl metals.
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.
