Anomalous hall effect
We present a review of experimental and theoretical studies of the anomalous Hall effect (AHE), focusing on recent developments that have provided a more complete framework for understanding this…
Doping a Mott insulator: Physics of high-temperature superconductivity
This article reviews the physics of high-temperature superconductors from the point of view of the doping of a Mott insulator. The basic electronic structure of cuprates is reviewed, emphasizing the…
Topological properties and dynamics of magnetic skyrmions.
From this description, potential applications of skyrmions as information carriers in magnetic information storage and processing devices are envisaged.
Real-space observation of a two-dimensional skyrmion crystal
Real-space imaging of a two-dimensional skyrmion lattice in a thin film of Fe0.5Co 0.5Si using Lorentz transmission electron microscopy reveals a controlled nanometre-scale spin topology, which may be useful in observing unconventional magneto-transport effects.
Classification of stable three-dimensional Dirac semimetals with nontrivial topology.
A general framework to classify stable 3D Dirac SMs in systems having the time-reversal, inversion and uniaxial rotational symmetries is proposed and it is shown that there are two distinct classes of DiracSMs.
Giant Rashba-type spin splitting in bulk BiTeI.
The finding of a huge spin-orbit interaction effect in a polar semiconductor composed of heavy elements, BiTeI, where the bulk carriers are ruled by large Rashba-likespin splitting is described, confirming that the spin splitting is indeed derived from bulk atomic configurations.
The Anomalous Hall Effect and Magnetic Monopoles in Momentum Space
It is shown that the magnetic monopole can appear in the crystal momentum space of solids in the accessible low-energy region in the context of the anomalous Hall effect.

Recent technical advances in the atomic-scale synthesis of oxide heterostructures have provided a fertile new ground for creating novel states at their interfaces, with characteristic feature is the reconstruction of the charge, spin and orbital states at interfaces on the nanometre scale.
Hall effect of light.
The semiclassical equation of motion for the wave packet of light is derived taking into account the Berry curvature in momentum-space, which leads to the shift of wave-packet motion perpendicular to the gradient of the dielectric constant, i.e., the polarization-dependent Hall effect of light.
Theory of the thermal Hall effect in quantum magnets.
A theory of the thermal Hall effect in insulating quantum magnets, where the heat current is totally carried by charge-neutral objects such as magnons and spinons, offers a clear experimental method to prove the existence of the deconfined spinons via a thermal transport phenomenon.
