Electronic structure of Mott-insulator CaCu3Ti4O12: Photoemission and inverse photoemission study
H. J. Im, M. Iwataki, S. Yamazaki +10
We have performed the photoemission and inverse photoemission experiments to elucidate the origin of Mott insulating states in A-site ordered perovskite CaCuTiO (CCT…
Strong Correlation Effects of A-site Ordered Perovskite CaCu3Ti4O12 revealed by Angle-Resolved Photoemission Spectroscopy
H. J. Im, M. Tsunekawa, T. Sakurada +8
We report angle-resolved photoemission spectroscopy (ARPES) results of A-site ordered perovskite CaCuTiO. We have observed the clear band dispersions, which are shif…
Theory of Metal-Insulator Transition in PrRu4P12 and PrFe4P12
S. H. Curnoe, H. Harima, K. Takegahara +1
All symmetry allowed couplings between the 4f^2-electron ground state doublet of trivalent praseodymium in PrRu4P12 and PrFe4P12 and displacements of the phosphorus, iron or ruthen…
Mutual Experimental and Theoretical Validation of Bulk Photoemission Spectra of Sr1-xCaxVO3
A. Sekiyama, H. Fujiwara, S. Imada +14
We report high-resolution high-energy photoemission spectra together with parameter-free LDA+DMFT (local density approximation + dynamical mean-field theory) results for Sr1-xCaxVO…
Genuine Electronic States of Vanadium Perovskites Revealed by High-Energy Photoemission
A. Sekiyama, H. Fujiwara, S. Imada +6
Bulk-sensitive high-resolution photoemission was carried out on a prototype 3d1 metallic Sr1-xCaxVO3. In a strong contrast to so far reported results, the bulk spectral functions a…
