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…
High-field phase diagram of the chiral-lattice antiferromagnet Sr(TiO)Cu4(PO4)4
Toshihiro Nomura, Yasuyuki Kato, Yukitoshi Motome +9
High-field phase diagram of a chiral-lattice antiferromagnet Sr(TiO)Cu4(PO4)4 is studied by means of the ultrasound, dielectric, and magnetocaloric-effect measurements. These exper…
Magnetic bubble crystal in tetragonal magnets
Satoru Hayami, Yasuyuki Kato
A magnetic bubble crystal is a two-dimensional soliton lattice consisting of multiple spin density waves similar to a magnetic skyrmion crystal. Nevertheless, the emergence of the…
Ground-State Phase Diagram of the Kitaev-Heisenberg Model on a Three-dimensional Hyperhoneycomb Lattice
Kiyu Fukui, Yasuyuki Kato, Yukitoshi Motome
The Kitaev model, which hosts a quantum spin liquid (QSL) in the ground state, was originally defined on a two-dimensional honeycomb lattice, but can be straightforwardly extended…
