Symmetry analysis of current-induced switching of antiferromagnets
Hikaru Watanabe, Youichi Yanase
Antiferromagnets are robust to external electric and magnetic fields, and hence are seemingly uncontrollable. Recent studies, however, realized the electrical manipulations of anti…

Group-theoretical classification of multipole order: emergent responses and candidate materials
Hikaru Watanabe, Youichi Yanase
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 sp…

Theory of orbital magnetic quadrupole moment and magnetoelectric susceptibility
Atsuo Shitade, Hikaru Watanabe, Youichi Yanase
We derive a quantum-mechanical formula of the orbital magnetic quadrupole moment (MQM) in periodic systems by using the gauge-covariant gradient expansion. This formula is valid fo…
