Theoretical study of the crystal structure of the bilayer nickel oxychloride SrNiOCl and analysis of possible unconventional superconductivity
Masayuki Ochi, Hirofumi Sakakibara, Hidetomo Usui +1
The discovery of superconductivity under high pressure with exceeding 80 K in a bilayer nickelate LaNiO has led to a strong desire to realize similar high p…
Theoretical study of spin-fluctuation-mediated superconductivity in two-dimensional Hubbard models with an incipient flat band
Tetsuaki Aida, Karin Matsumoto, Daisuke Ogura +2
One promising way to enhance superconductivity is to have coexisting wide and incipient narrow bands, where the Fermi level intersecting the wide band lies just above the narrow ba…
Fermi Surface Nesting Driving the RKKY Interaction in the Centrosymmetric Skyrmion Magnet Gd2PdSi3
Yuyang Dong, Yosuke Arai, Kenta Kuroda +11
The magnetic skyrmions generated in a centrosymmetric crystal were recently first discovered in Gd2PdSi3. In light of this, we observe the electronic structure by angle-resolved ph…
Theoretical study on the possibility of high s-wave superconductivity in the heavily hole-doped infinite layer nickelates
Hirofumi Sakakibara, Ryota Mizuno, Masayuki Ochi +2
We theoretically propose a possibility of realizing high superconductivity having -wave symmetry in the heavily hole-doped infinite layer nickelates LaSrNiO…
Theoretical analysis of the origin of the double-well band dispersion in the CuO double chains of PrBaCuO and its impact on superconductivity
Toshiki Yagi, Masayuki Ochi, Kazuhiko Kuroki
PrBaCuO is a unique member of cuprate superconductors where many studies suggest that CuO double chains are responsible for superconductivity. One characterist…
Anomalous Fermi pockets on Hund's metal surface of Sr2RuO4 induced by the correlation-enhanced spin-orbit coupling
Takeshi Kondo, Masayuki Ochi, Shuntaro Akebi +4
The electronic structure of the topmost layer in Sr2RuO4 in the close vicinity of the Fermi level is investigated by angle-resolved photoemission spectroscopy (ARPES) with a 7-eV l…
