Topological phase transitions by time-dependent electromagnetic fields in frustrated magnets: Role of dynamical and static magnetic fields
Tatsuya Shirato, Ryota Yambe, Satoru Hayami
We theoretically investigate the effects of time-dependent electromagnetic fields on frustrated magnets with the spatial inversion symmetry. Two types of external-field setups are…
Symmetry Rules on Multipole Interactions under Crystallographic Point Groups and Application to Multiple- Multipole States
Ryota Yambe, Satoru Hayami
Multipole degrees of freedom describe the mutual interplay among the charge, spin, and orbital degrees of freedom in electrons, which provides a microscopic understanding of unconv…
Bimeron Crystals by a Linearly Polarized AC Electric Field in Frustrated Magnets
Tatsuya Shirato, Ryota Yambe, Satoru Hayami
We theoretically propose a method to generate topological spin textures by irradiating a classical spin system with a linearly polarized AC electric field. To this end, we investig…
Stabilization mechanisms of magnetic skyrmion crystal and multiple- states based on momentum-resolved spin interactions
Satoru Hayami, Ryota Yambe
Multiple- states as represented by a magnetic skyrmion crystal and hedgehog crystal have been extensively studied in recent years owing to their unconventional physical properti…
Dynamical generation of skyrmion and bimeron crystals by a circularly polarized electric field in frustrated magnets
Ryota Yambe, Satoru Hayami
A skyrmion crystal (SkX) has attracted much attention in condensed matter physics, since topologically nontrivial structures induce fascinating physical phenomena. The SkXs have be…
Scalar spin chirality induced by a circularly polarized electric field in a classical kagome magnet
Ryota Yambe, Satoru Hayami
Noncoplanar magnetic states with a scalar spin chirality have been intensively studied in condensed matter physics, since they exhibit fascinating physical phenomena. We theoretica…
