Stability-threshold control of helicity-selective antiferromagnetic resonance
Masato Todani, Satoshi Iihama, Yuto Moritake +1
We study helicity-selective antiferromagnetic resonance in an antiferromagnetic-insulator/nonmagnetic-metal junction with sublattice-dependent damping and spin-orbit torque. By for…
Microscopic derivation of the microstretch theory for carbon nanotubes
Naoki Nishimura, Mamoru Matsuo, Takeo Kato
Twisted carbon nanotubes support phonons involving not only torsion, naturally associated with microrotation, but also radial breathing, which requires a scalar stretch degree of f…
Two-body loss dynamics as a probe of dynamical bulk viscosity in ultracold atomic gases
Tingyu Zhang, Hiroyuki Tajima, Takeo Kato
We show that the equilibrium connected correlation of the two-body loss rate provides access to the dynamical bulk viscosity in weakly dissipative quantum gases. Starting from the…
Spin Peltier effect in graphene
Xin Theng Lee, Xin Hu, Yuya Ominato +3
In this work, we theoretically investigate the spin-Peltier effect in a heterostructure composed of graphene and a ferromagnetic insulator (FI). Using a microscopic formalism based…
Spin Seebeck effect in magnetic junctions with a compensated ferrimagnet
Xin Theng Lee, Takahiro Misawa, Mamoru Matsuo +1
Compensated ferrimagnets enable ferromagnet-like spin transport without net magnetization. We study the spin Seebeck effect in a compensated ferrimagnet/normal-metal junction using…
Generalized continuum theory of phonon angular momentum in crystals
Mamoru Matsuo, Naoki Nishimura, Ai Yamakage +1
We formulate a generalized continuum theory of phonon angular momentum in crystals by introducing a local SO(3) material frame in addition to the macroscopic displacement field. Th…
