The body of research on (III,Mn)V diluted magnetic semiconductors (DMSs) initiated during
the 1990s has concentrated on three major fronts: (i) the microscopic origins and …

The recent development of MBE techniques for growth of III–V ferromagnetic semiconductors
has created materials with exceptional promise in spintronics, that is, electronics that …

The anomalous Hall effect (AHE) occurs in solids with broken time-reversal symmetry,
typically in a ferromagnetic phase, as a consequence of spin-orbit coupling. Experimental and …

We present a theory of the anomalous Hall effect in ferromagnetic (III, Mn) V semiconductors.
Our theory relates the anomalous Hall conductance of a homogeneous ferromagnet to the …

We present a theory of the collective excitation spectrum in the fractional quantum Hall
effect which is closely analogous to Feynman’s theory of superfluid helium. The predicted …

The authors describe a fully relativistic augmented-plane-wave (APW) method where the
basis functions are pure spin functions in the large component. This feature allows spin-mixing …

We perform a first principles calculation of the anomalous Hall effect in ferromagnetic bcc Fe.
Our theory identifies an intrinsic contribution to the anomalous Hall conductivity and relates …

A moiré pattern is formed when two copies of a periodic pattern are overlaid with a relative
twist. We address the electronic structure of a twisted two-layer graphene system, showing …

At strong magnetic fields, double-layer two-dimensional electron-gas systems can form an
unusual broken-symmetry state with spontaneous interlayer phase coherence. In this paper …

We describe a new effect in semiconductor spintronics that leads to dissipationless spin
currents in paramagnetic spin-orbit coupled systems. We argue that in a high-mobility two-…
