Translational symmetry breaking in the electronic nematic phase of BaFe2As2
K. Koshiishi, L. Liu, K. Okazaki +13
The microscopic origin of the nematicity, namely, four-fold rotational symmetry breaking in iron-based superconductors has been controversial since its discovery. In particular, it…
Large Seebeck coefficient driven by "pudding mold" flat band in hole-doped CuRhO
Amitayush Jha Thakur, Maximilian Thees, Franck Fortuna +7
We report the measurement, using angle-resolved photoemission spectroscopy, of the metallic electronic structure of the hole-doped thermoelectric oxide CuRhMgO.…
Out-of-phase Plasmon Excitations in the Trilayer Cuprate BiSrCaCuO
S. Nakata, M. Bejas, J. Okamoto +14
Within a homologous series of cuprate superconductors, variations in the stacking of CuO layers influence the collective charge dynamics through the long-range Coulomb interact…
On the cuprates' universal waterfall feature: evidence of a momentum-driven crossover
Benjamin Bacq-Labreuil, Chafic Fawaz, Yuichi Okazaki +13
We study two related universal anomalies of the spectral function of cuprates, so called waterfall and high-energy kink features, by a combined cellular dynamical mean-field theory…
