We overview recent developments of electronic orderings and associated cross correlations
in condensed matter physics based on a complete set of multipole representations (electric …

We theoretically report an instability toward a skyrmion crystal in centrosymmetric magnets

The nature of an electric ferroaxial moment characterizing a time-reversal-even axial-vector
quantity is theoretically investigated under magnetic orderings. We clarify that a vortex spin …

A mutual interplay between the charge and spin degrees of freedom in itinerant magnets
leads to a plethora of topological spin textures, such as magnetic skyrmion and vortex …
