Hybridization driving distortions and multiferroicity in rare-earth nickelates
Nicola Marzari, Iurii Timrov, Michele Kotiuga, Luca Binci
For decades transition-metal oxides have generated a huge interest due to the multitude of physical phenomena they exhibit. In this class of materials, the rare-earth nickelates, RNiO3, stand out for their rich phase diagram stemming from complex couplings ...
College Pk2023Can dd excitations mediate pairing?
Christophe Berthod, Francesco Barantani
The Cu-3d states in the high-T-c cuprates are often described as a single band of 3d(x2-y2) states, with the other four 3d states having about 2 to 3 eV higher energy due to the lower-than-octahedral crystal field at the copper sites. However, excitations ...

The microscopic mechanism of heavy band formation, relevant for unconventional superconductivity in CeCoIn5 and other Ce-based heavy fermion materials, depends strongly on the efficiency with which f electrons are delocalized from the rare earth sites and ...
