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…
Multi-step topological transitions among meron and skyrmion crystals in a centrosymmetric magnet
H. Yoshimochi, R. Takagi, J. Ju +10
Topological swirling spin textures, such as skyrmions and merons, have recently attracted much attention as a unique building block for high-density magnetic information devices. T…
Hybrid skyrmion and anti-skyrmion phases in polar systems
Satoru Hayami
We investigate the stability of the skyrmion crystal phase in a tetragonal polar system with the Dzyaloshinskii-Moriya interaction by focusing on the symmetry of ordering wave vect…
Rotational Response Induced by Electric Toroidal Dipole
Akimitsu Kirikoshi, Satoru Hayami
A ferroaxial ordering, which appears without mirror symmetry parallel to an electric axial moment, is described by a ferroic alignment of the electric toroidal (ET) dipole rather t…
Symmetry-adapted modeling for molecules and crystals
Hiroaki Kusunose, Rikuto Oiwa, Satoru Hayami
We have developed a symmetry-adapted modeling procedure for molecules and crystals. By using the completeness of multipoles to express spatial and time-reversal parity-specific ani…
Anisotropic spin model and multiple- states in cubic systems
Ryota Yambe, Satoru Hayami
Multiple- states manifest themselves in a variety of noncollinear and noncoplanar magnetic structures depending on the magnetic interactions and lattice structures. In particula…
