Anomalous charge transport upon quantum melting of chiral spin order
Y. Fujishiro, C. Terakura, A. Miyake +11
A plethora of correlated and exotic metallic states have been identified on the border of itinerant magnetism, where the long-range spin texture is melted by tuning the magnetic tr…
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…
Ground-state phase diagram of spin- Kitaev-Heisenberg models
Kiyu Fukui, Yasuyuki Kato, Joji Nasu +1
The Kitaev model, whose ground state is a quantum spin liquid (QSL), was originally conceived for spin moments on a honeycomb lattice. In recent years, the model has been e…
Asymmetric modulation of Majorana excitation spectra and nonreciprocal thermal transport in the Kitaev spin liquid under a staggered magnetic field
Kazuki Nakazawa, Yasuyuki Kato, Yukitoshi Motome
We present the theoretical results for the Majorana band structure and thermal transport properties in the Kitaev honeycomb model under a staggered magnetic field in addition to a…
Magnetoelectric Behavior from Asymmetric Square Cupolas
Yasuyuki Kato, Kenta Kimura, Atsushi Miyake +8
Magnetoelectric properties are studied by a combined experimental and theoretical study of a quasi-two-dimensional material composed of square cupolas, Ba(TiO)Cu(PO). T…
Cubic-quintic nonlinearity in superfluid Bose-Bose mixtures in optical lattices: Heavy solitary waves, barrier-induced criticality, and current-phase relations
Ippei Danshita, Daisuke Yamamoto, Yasuyuki Kato
We study superfluid (SF) states of strongly interacting Bose-Bose mixtures with equal mass and intra-component interaction in optical lattices both in the presence and absence of a…
