The role of the apical oxygen in cuprate high-temperature superconductors
Samuel Vadnais, Rémi Duchesne, Kristjan Haule +3
Scanning tunneling microscopy measurements exploiting the natural superstructure modulation of the cuprate superconductor BiSrCaCuO (Bi-2212) have revealed a p…
Magnetic excitons in a suspended 2D antiferromagnetic membrane
Joanna L. P. Wolff, Loïc Moczko, Jérémy Thoraval +4
Layered magnetic and strongly correlated materials present a rich platform for condensed matter physics with intrinsic properties intertwined by magnetism and low-dimensionality. A…
Towards an ab initio theory of high-temperature superconductors: a study of multilayer cuprates
Benjamin Bacq-Labreuil, Benjamin Lacasse, André-Marie S. Tremblay +2
Significant progress towards a theory of high-temperature superconductivity in cuprates has been achieved via the study of effective one- and three-band Hubbard models. Nevertheles…
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…
