Electric-field-induced magnetic toroidal moment and nonlinear magnetoelectric effect in antiferromagnetic olivines
Yasuyuki Kato, Takeshi Hayashida, Koei Matsumoto +2
Beyond conventional electric and magnetic monopoles, electric and magnetic toroidal monopoles, which are rank-0 multipoles distinguished by opposite parities under spatial inversio…

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…

Spin Seebeck Effect as a Probe for Majorana Fermions in Kitaev Spin Liquids
Yasuyuki Kato, Joji Nasu, Masahiro Sato +3
Quantum entanglement in strongly correlated electron systems often leads to exotic elementary excitations. Quantum spin liquids (QSLs) provide a paradigmatic example, where the ele…
