Excitonic Bose-Einstein condensation in Ta2NiSe5 above room temperature
K. Seki, Y. Wakisaka, T. Kaneko +12
We show that finite temperature variational cluster approximation (VCA) calculations on an extended Falicov-Kimball model can reproduce angle-resolved photoemission spectroscopy (A…
High-temperature thermoelectric properties of the double-perovskite ruthenium oxide (SrLa)ErRuO
Ryohei Takahashi, Ryuji Okazaki, Yukio Yasui +7
We have prepared polycrystalline samples of (SrLa)ErRuO and (SrLa)YRuO, and have measured the resistivity, Seebeck coefficient, thermal cond…
Anomalous momentum dependence of the multiband electronic structure of FeSe_1-xTe_x superconductors induced by atomic disorder
Takaaki Sudayama, Yuki Wakisaka, Daiki Ootsuki +7
When periodicity of crystal is disturbed by atomic disorder, its electronic state becomes inhomogeneous and band dispersion is obscured. In case of Fe-based superconductors, disord…
Magnetic Frustration in a Mn Honeycomb Lattice Induced by Mn-O-O-Mn Pathways
H. Wadati, K. Kato, Y. Wakisaka +9
We investigated the electronic structure of layered Mn oxide Bi3Mn4O12(NO3) with a Mn honeycomb lattice by x-ray absorption spectroscopy. The valence of Mn was determined to be 4+…
