Light-induced nonlinear Edelstein effect under ferroaxial ordering
Akimitsu Kirikoshi, Satoru Hayami
Ferroaxial ordering, a spontaneous rotational distortion of the atomic arrangement, brings about a cross-product-type spin-orbit coupling (SOC) manifested as an electric toroidal d…
Multiple- spin textures induced by spiral--staggered interference in one-dimensional itinerant magnets
Satoru Hayami, Kazuki Okigami
We theoretically investigate multiple- magnetic states emerging from the interference between finite- spiral and staggered spin modulations in a one-dimensional itinerant ele…
Spinless electric toroidal multipoles in ferroaxial revealed by symmetry-adapted closest Wannier analysis
Yu Xie, Rikuto Oiwa, Satoru Hayami
From a symmetry perspective, ferroaxial order belongs to the same symmetry as time-reversal-even pseudovectors. Experimentally, is known to undergo a displaci…
Four-Spin Interactions as a Route to Multiple-Q Topological Magnetic Order
Kazuki Okigami, Satoru Hayami
We investigate the role of four-spin interactions in stabilizing exotic multiple- topological spin textures and demonstrate their ability to realize a skyrmion crystal. While su…
Finite- antiferrotoroidal and ferritoroidal order in a distorted kagome structure
Akimitsu Kirikoshi, Satoru Hayami
A highly geometrically frustrated lattice structure such as a distorted kagome (or quasikagome) structure enriches physical phenomena through coupling with the electronic structure…
Perfectly harmonic spin cycloid and multi- textures in the Weyl semimetal GdAlSi
Ryota Nakano, Rinsuke Yamada, Juba Bouaziz +18
A fundamental question concerns how topological electronic states are influenced by many-body correlations, and magnetic Weyl semimetals represent an important material platform to…
