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 phase diagram of the Haldane model on a Bishamon-kikko--honeycomb lattice
Sogen Ikegami, Kiyu Fukui, Shun Okumura +2
Topological flat bands have gained extensive interest as a platform for exploring the interplay between nontrivial band topology and correlation effects. In recent studies, strongl…
Video recognition by physical reservoir computing in magnetic materials
Kaito Kobayashi, Yukitoshi Motome
Nonlinear spin dynamics in magnetic materials offers a promising avenue for implementing physical reservoir computing, one of the most accomplished brain-inspired frameworks for in…
Emergent electric field from magnetic resonances in a one-dimensional chiral magnet
Kotaro Shimizu, Shun Okumura, Yasuyuki Kato +1
The emergent electric field (EEF) is a fictitious electric field acting on conduction electrons through the Berry phase mechanism. The EEF is generated by the dynamics of noncollin…
