Journal ArticleDOI
Temperature dependence of carrier spin polarization determined from current-induced domain wall motion in a Co/Ni nanowire
Kohei Ueda,Tomohiro Koyama,Ryo Hiramatsu,Daichi Chiba,Shunsuke Fukami,H. Tanigawa,Tetsuhiro Suzuki,Norikazu Ohshima,Nobuyuki Ishiwata,Yoshinobu Nakatani,Kensuke Kobayashi,Teruo Ono +11 more
TL;DR: In this paper, the authors investigated the temperature dependence of the current-induced magnetic domain wall motion in a perpendicularly magnetized Co/Ni nanowire at various temperatures and with various applied currents.
Journal ArticleDOI
Observation of "partial coherence" in an Aharonov-Bohm interferometer with a quantum dot.
TL;DR: Evidence of "partial coherence" due to an entanglement of spins in the QD and in the interferometer is reported, and the asymmetry in the amplitude around the two Coulomb peaks agrees with the theoretical prediction that the spin-flip process in a QD is related to the quantum dephasing of electrons.
Journal ArticleDOI
Observation of Coulomb-Assisted Nuclear Bound State of Ξ^{-}-^{14}N System.

TL;DR: In an emulsion-counter hybrid experiment performed at J-PARC, a Ξ^{-} absorption event was observed which decayed into twin single-Κ hypernuclei which indicates a weak ΞN-ΛΛ coupling.
Journal ArticleDOI
Dynamical Pinning of a Domain Wall in a Magnetic Nanowire Induced by Walker Breakdown
H. Tanigawa,Tomohiro Koyama,Maciej Bartkowiak,Shinya Kasai,Kensuke Kobayashi,Teruo Ono,Yoshinobu Nakatani +6 more
TL;DR: The micromagnetics simulation reveals that the domain wall motion in the wire with finite roughness causes the dynamical pinning due to the Walker breakdown, which semiquantitatively explains the experimental results.
Journal ArticleDOI
Quantum Fluctuations along Symmetry Crossover in a Kondo-Correlated Quantum Dot
Meydi Ferrier,Meydi Ferrier,Tomonori Arakawa,Tokuro Hata,Ryo Fujiwara,Raphaelle Delagrange,R. Deblock,Yoshimichi Teratani,Rui Sakano,Akira Oguri,Kensuke Kobayashi +10 more
TL;DR: This work modified quantum fluctuations to directly measure their influence on the many-body properties along the crossover from SU(4) to SU(2) symmetry of the ground state, demonstrating that nonlinear noise constitutes a measure of quantum fluctuations that can be used to tackle quantum phase transitions.
