The intrinsic anomalous Hall effect in metallic ferromagnets is shown to be controlled by Berry phases accumulated by adiabatic motion of quasiparticles on the Fermi surface, and is purely a Fermi-liquid property, not a bulk Fermi sea property like Landau diamagnetism, as has been previously supposed. Berry phases are a new topological ingredient that must be added to Landau Fermi-liquid theory in the presence of broken inversion or time-reversal symmetry.

Anomalous Hall effect in a two-dimensional electron gas with spin-orbit interaction
We discuss the mechanism of anomalous Hall effect related to the contribution of electron states below the Fermi surface induced by the Berry phase in momentum space. Our main calculations are made
Attractive electron-electron interaction induced by geometric phase in a Bloch band
We investigate electron pairing in the presence of the Berry curvature field that ubiquitously exists in ferromagnetic metals with spin-orbit coupling. We show that a sufficiently strong Berry

The Landau Fermi liquid[2], along with certain types of non-Fermi liquids[3], is characterized by a large emergent symmetry: the charge at each momentum on the Fermi surface is conserved at low
Collective dynamics of Fermi surface fluctuations in an interacting Weyl metal phase
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 chiral anomaly

An analysis of the stability of topological states induced by Coulomb repulsion on decorated honeycomb lattices is presented. Based on a mean-field treatment of a spinless extended Hubbard model on
Berry phase in the composite Fermi liquid
We derive the definition of the Berry phase for the adiabatic transport of a composite fermion (CF) in a half-filled composite Fermi-liquid (CFL). It is found to be different from that adopted in

The anomalous Hall effect and spin Hall effect originate due to spin-orbit coupling that in the Kohn-Luttinger k · p formalism is represented by anomalous terms in the coordinate and velocity

We calculate the anomalous Hall conductance of superconductors with spin-orbit interaction and with either uniform or local magnetization. In the first case we consider a uniform ferromagnetic
Berry phase in composite Fermi liquids
Two-dimensional electron gas in high magnetic field exhibits a wide variety of interesting physical properties. Perhaps most notable of these is the quantum Hall effect, which is a classic example of
Anomalous Hall effect and Berry phase in two-dimensional magnetic structures
We discuss the topological character of the anomalous Hall effect in two different models of the electron energy spectrum. The essential property of each of these models is the nontrivial topology of
