Observation of Electronic Structure Modification in the Hidden Order Phase of CeCoSi
Shin-ichi Kimura, Hiroshi Watanabe, Shingo Tatsukawa +1
CeCoSi with no local inversion symmetric crystal structure () exhibits a phase transition of unknown origin (Hidden Order: HO) at about 12 K () above the antiferromagn…
Monte Carlo study of cuprate superconductors in a four-band - model: Role of orbital degrees of freedom
Hiroshi Watanabe, Tomonori Shirakawa, Kazuhiro Seki +4
Understanding the complex phase diagram of cuprate superconductors is a long-standing challenging problem. Recent studies have shown that orbital degrees of freedom, both Cu …
Spin canting in nonlinear terahertz magnon dynamics revealed by magnetorefractive probing in orthoferrite
Takayuki Kurihara, Motoaki Bamba, Hiroshi Watanabe +2
We excite the spin precession in rare-earth orthoferrite YFeO3 by the magnetic field of intense terahertz pulse and probe its dynamics by transient absorption change in the near in…
Unified description of cuprate superconductors using four-band - model
Hiroshi Watanabe, Tomonori Shirakawa, Kazuhiro Seki +4
In the 35 years since the discovery of cuprate superconductors, we have not yet reached a unified understanding of their properties, including their material dependence of the supe…
Bulk-Sensitive Spin-Resolved Resonant Electron Energy-Loss Spectroscopy (SR-rEELS): Observation of Element- and Spin-Selective Bulk Plasmons
Shin-ichi Kimura, Taishi Kawabata, Hiroki Matsumoto +8
We have developed a spin-resolved resonant electron energy-loss spectroscopy (SR-rEELS) in the primary energy of 0.3--1.5 keV, which corresponds to the core excitations of -$3d…
One-dimensionality of the spin-polarized surface conduction and valence bands of quasi-one-dimensional Bi chains on GaSb(110)-(21)
Yoshiyuki Ohtsubo, Naoki Tokumasu, Hiroshi Watanabe +8
Surface electronic structure and its one-dimensionality above and below the Fermi level () were surveyed on the Bi/GaSb(110)-(21) surface hosting quasi-one-dimen…
