Optical Hall response in spin-orbit coupled metals: Comparative study of magnetic cluster monopole, quadrupole, and toroidal orders
Tatsuki Sato, Yuma Umimoto, Yusuke Sugita +2
The optical Hall response is theoretically studied for spin-orbit coupled metals with ferroic orders of cluster-type magnetic multipoles. We find that different magnetic multipoles…
Phase transitions between helices, vortices, and hedgehogs driven by spatial anisotropy in chiral magnets
Kotaro Shimizu, Shun Okumura, Yasuyuki Kato +1
Superpositions of spin helices can yield topological spin textures, such as two-dimensional vortices and skyrmions, and three-dimensional hedgehogs. Their topological nature and sp…
Spin moiré engineering of topological magnetism and emergent electromagnetic fields
Kotaro Shimizu, Shun Okumura, Yasuyuki Kato +1
A superposition of spin helices can yield topological spin textures, such as skyrmion and hedgehog lattices. Based on the analogy with the moiré in optics, we study the magnetic an…
Thermodynamic classification of three-dimensional Kitaev spin liquids
Tim Eschmann, Petr A. Mishchenko, Kevin O'Brien +5
In the field of frustrated magnetism, Kitaev models provide a unique framework to study the phenomena of spin fractionalization and emergent lattice gauge theories in two and three…
Magnetic-field-induced tunability of spin Hamiltonians: Resonances and Efimov states in YbTiO
Yasuyuki Kato, Shang-Shun Zhang, Yusuke Nishida +1
Universality is a powerful concept that arises from the divergence of a characteristic length scale. For condensed matter systems, this length scale is typically the correlation le…
Materials design of Kitaev spin liquids beyond the Jackeli-Khaliullin mechanism
Y. Motome, R. Sano, S. -H. Jang +2
The Kitaev spin liquid provides a rare example of well-established quantum spin liquids in more than one dimension. It is obtained as the exact ground state of the Kitaev spin mode…
