Antisymmetric linear transverse magnetization and ferroaxial moments induced by geometry-driven electric field gradients
Akane Inda, Satoru Hayami
We theoretically investigate the transverse magnetization and ferroaxial moments induced by electric field gradients arising from the geometry of finite systems. Based on the Kubo…
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…
