Spin torque due to diffusive spin current in magnetic texture
Kazuhiro Hosono, Junya Shibata, Hiroshi Kohno +1
We present a microscopic theory of spin torque due to diffusive spin currents induced by spin accumulation. The obtained expression is a natural extension of the existing one due t…

Generation of spin-polarized current using multi-terminated quantum dot with spin-orbit interaction
Tomohiro Yokoyama, Mikio Eto
We theoretically examine generation of spin-polarized current using multi-terminated quantum dot with spin-orbit interaction. First, a two-level quantum dot is analyzed as a minima…

Optical Phonon Lasing in Semiconductor Double Quantum Dots
Rin Okuyama, Mikio Eto, Tobias Brandes
We propose optical phonon lasing for a double quantum dot (DQD) fabricated in a semiconductor substrate. We show that the DQD is weakly coupled to only two LO phonon modes that act…
