Wavepacket Approach for Spin Transport in Zigzag Spin Chain
Hiroaki Onishi
We study the spin transport property of a spin nematic liquid in a frustrated zigzag spin chain in a magnetic field from the perspective of the time evolution of wavepackets by a t…
Finite-temperature properties of extended Nagaoka ferromagnetism
Hiroaki Onishi, Seiji Miyashita
We study finite-temperature properties of a Hubbard model including sites of a particle bath which was proposed as a microscopic model to show itinerant ferromagnetism at finite el…
Excitation and transport of bound magnon clusters in frustrated ferromagnetic chain
Hiroaki Onishi
We investigate magnetic excitations and spin transport properties of a frustrated spin chain with ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor exchang…
Magnetic excitations and transport properties in frustrated ferromagnetic chain
Hiroaki Onishi
To clarify the transport property mediated by bound magnons in a spin nematic state, we investigate the spin Drude weight of a spin-1/2 - Heisenberg chain with ferrom…
Dynamical quadrupole structure factor of frustrated ferromagnetic chain
Hiroaki Onishi
We investigate the dynamical quadrupole structure factor of a spin-1/2 - Heisenberg chain with competing ferromagnetic and antiferromagnetic in a magn…
Neutron-scattering study of yttrium iron garnet
Shin-ichi Shamoto, Takashi U. Ito, Hiroaki Onishi +13
The nuclear and magnetic structure and full magnon dispersions of yttrium iron garnet YFeO have been studied by neutron scattering. The refined nuclear structure is…
