We propose an efficient microscopic design procedure of electronic band structures having
intrinsic spin and momentum dependences in spin-orbit-coupling free antiferromagnets. Our …

Rectified electric current induced by irradiating light, a so-called photocurrent, is an
established phenomenon in optoelectronic physics. In this paper, we present a …

Four types of atomic-scale multipoles (electric, magnetic, magnetic toroidal, and electric
toroidal multipoles) give a complete set to describe arbitrary degrees of freedom for coupled …

The multipole moment is an established concept of electrons in solids. Entanglement of spin,
orbital, and sublattice degrees of freedom is described by the multipole moment, and …

Mutual interplay between the electronic degrees of freedom in solids, such as charge, spin,
orbital, sublattice, and bond degrees of freedom, is a source of cross-correlated phenomena …

Spatial inversion symmetry in crystal structures is closely related to the superconducting
(SC) and magnetic properties of materials. Recently, several theoretical proposals that …

Toroidal order, given by a composite of electric and magnetic orders, manifests itself not only
in unusual magnetism but also in anomalous transport and magnetoelectric effects. We …

Violation of parity symmetry gives rise to various physical phenomena such as nonlinear
transport and cross-correlated responses. In particular, the nonlinear conductivity has been …

We theoretically investigate an intrinsic nonlinear anomalous Hall effect (INAHE) in space-
time (PT) symmetric antiferromagnetic metals. The INAHE is characterized by an asymmetric …

Nonreciprocal directional dichroism (NDD) is a phenomenon in which the optical absorption
is changed by reversing the direction of light propagation or the sign of the magnetic order …
