Dynamical structure factors of S=1 bond-alternating Heisenberg chains
Takahumi Suzuki, Sei-ichiro Suga
We calculate the dynamical structural factor of the S=1 bond-alternating Heisenberg chain. In the Haldane phase, the lowest excited states form the lower edge of the multimagnon co…
Optical absorption spectra in SrCu_2O_3 two-leg spin ladder
Nobuyasu Haga, Sei-ichiro Suga
We calculate the phonon-assisted optical-absorption spectra in SrCu_2O_3 two-leg spin-ladder systems. The results for two models proposed for SrCu_2O_3 are compared. In the model i…
Effects of degenerate orbitals on the Hubbard model
Akihisa Koga, Takuma Ohashi, Yoshiki Imai +2
Stability of a metallic state in the two-orbital Hubbard model at half-filling is investigated. We clarify how spin and orbital fluctuations are enhanced to stabilize the formation…
Auger Effect in the High-Resolution Ce 3d-edge Resonant Photoemission
E. -J. Cho, R. -J. Jung, B. -H. Choi +8
The bulk-sensitive Ce 4 spectral weights of various Ce compounds including CeFe, CeNi, and CeSi were obtained with the resonant photoemission technique at the Ce 3d-…
Localized Character of 4f Electrons in CeRh(x=2,3) and CeNi(x=2,5)
Ran-Ju Jung, Byung-Hee Choi, Hyeong-Do Kim +7
We have measured Ce 4f spectral weights of extremely -like Ce-transition metal intermetallic compounds CeRh (x=2,3) and CeNi (x=2,5) by using the {\it bulk-sensitive} re…
