Spiral-induced anomalous Hall effect from odd-parity spin-nodal lines
Shun Okumura, Moritz M. Hirschmann, Yukitoshi Motome
Spin spirals represent a fundamental class of noncollinear yet coplanar magnetic structures that give rise to diverse emergent phenomena through their coupling to itinerant electro…
Nonequilibrium dynamics of magnetic hopfions driven by spin-orbit torque
Shoya Kasai, Shun Okumura, Yukitoshi Motome
Hopfions--three-dimensional topological solitons with knotted spin texture--have recently garnered attention in topological magnetism due to their unique topology characterized by…
Controlling Knot Topology in Magnetic Hopfions via Spin-orbit Torque
Shoya Kasai, Shun Okumura, Yukitoshi Motome
Knots, characterized by topological invariants called the Hopf number , arise from the intertwining of strings and exhibit diverse configurations. The knot structures have recen…
Topological transition induced by selective random defects on a honeycomb lattice
Sogen Ikegami, Kiyu Fukui, Shun Okumura +2
We investigate how the spectral and topological properties of electron systems evolve on a lattice that interpolates between the honeycomb and its 1/6-depleted structures through t…
Metallic -wave magnet with commensurate spin helix
Rinsuke Yamada, Max T. Birch, Priya R. Baral +20
Antiferromagnetic states with spin-split electronic structure give rise to novel spintronic, magnonic, and electronic phenomena despite (near-) zero net magnetization. The simplest…
