Spontaneous chirality selection and nonreciprocal spin wave in breathing-kagome antiferromagnets at zero field
Kazushi Aoyama, Hikaru Kawamura
It has been known that the spin-wave dispersion, which is usually symmetric in the momentum space with respect to , can be asymmetric in the presence of the Dzyaloshinsk…
Fractal and subharmonic responses driven by surface acoustic waves during charge density wave sliding
Yu Funami, Kazushi Aoyama
We theoretically investigate the effects of surface acoustic waves (SAWs) on an electric-field-driven sliding motion of a one-dimensional charge density wave (CDW), which is initia…
Zero-field miniature skyrmion crystal and chiral domain state in breathing-kagome antiferromagnets
Kazushi Aoyama, Hikaru Kawamura
The stability of a miniature skyrmion crystal (SkX) with only a small number of spins in the magnetic unit cell has been theoretically investigated in - antiferromagnets…
Spin and thermal transport and critical phenomena in three-dimensional antiferromagnets
Kazushi Aoyama
We investigate spin and thermal transport near the Néel transition temperature in three dimensions, by numerically analyzing the classical antiferromagnetic model on th…
Hedgehog lattice and field-induced chirality in breathing-pyrochlore Heisenberg antiferromagnets
Kazushi Aoyama, Hikaru Kawamura
We theoretically investigate a - classical Heisenberg model on the breathing pyrochlore lattice, where the nearest-neighbor (NN) exchange interactions for small and large…
Emergent skyrmion-based chiral order in zero-field Heisenberg antiferromagnets on the breathing kagome lattice
Kazushi Aoyama, Hikaru Kawamura
We show that classical Heisenberg antiferromagnets on the breathing kagome lattice can be a platform to realize a zero-field topological order of the scalar spin chirality which ca…
