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…
Half-quantum flux in spin-triplet superconducting rings with bias current
Kazushi Aoyama
Effects of a bias electric current have been theoretically investigated in a spin-triplet superconducting ring in a magnetic field. Based on the Ginzburg-Landau theory, we show tha…
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…
Signatures of a magnetic superstructure phase induced by ultrahigh magnetic fields in a breathing pyrochlore antiferromagnet
M. Gen, A. Ikeda, K. Aoyama +11
The mutual coupling of spin and lattice degrees of freedom is ubiquitous in magnetic materials and potentially creates exotic magnetic states in response to the external magnetic f…
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…
