Mechanism of intermetallic charge transfer and bond disproportionation in BiNiO and PbNiO revealed by hard x-ray photoemission spectroscopy
Tatsuya Yamaguchi, Mizuki Furo, Yuki Sakai +11
Perovskites with Bi or Pb on the A-site host a number of interesting and yet to be understood phenomena such as negative thermal expansion in BiNiO. We employ hard x-ray photoe…
Ferromagnetic clouds caused by hole motion in a one-dimensional - mode
Kazuhiro Sano, Ken'ichi Takano
The one-dimensional --- model is examined in the one-hole case, in which the total number of electrons is one less than the number of the lattice sites. The gro…
Anomalous Flux Quantization in the Spin-Imbalanced Attractive Hubbard Ring
Kazuhiro Sano, Yoshiaki Ono
We investigate the one-dimensional Hubbard ring with attractive interaction in the presence of imbalanced spin populations by using the exact diagonalization method. The singlet pa…
Bound state of a hole and a triplet spin in the --- model
Kazuhiro Sano, Ken'ichi Takano
We show that a hole and a triplet spin form a bound state in a nearly half-filled band of the one- and two-dimensional --- models. Numerical calculation indicat…
Superconductivity in a Two-Orbital Hubbard Model with Electron and Hole Fermi Pockets: Application in Iron Oxypnictide Superconductors
Kazuhiro Sano, Yoshiaki Ono
We investigate the electronic states of a one-dimensional two-orbital Hubbard model with band splitting by the exact diagonalization method. The Luttinger liquid parameter is…
Soft x-ray magnetic circular dichroism study of Ca_1-xSr_xRuO_3 across the ferromagnetic quantum phase transition
J. Okamoto, T. Okane, Y. Saitoh +10
Ca_1-xSr_xRuO_3, which is ferromagnetic for Sr concentration x > 0.3, has been studied by x-ray magnetic circular dichroism (XMCD) in Ru 3p and O 1s core-level x-ray absorption. XM…
