Spin and orbital excitations in undoped infinite layers: a comparison between superconducting PrNiO2 and insulating CaCuO2
Francesco Rosa, Hoshang Sahib, Giacomo Merzoni +9
Infinite-layer nickelates are among the most promising cuprate-akin superconductors, although relevant differences from copper oxides have been reported. Here, we present momentum-…

Anomalous Eigenstates of a Doped Hole in the Ising Antiferromagnet
Piotr Wrzosek, Krzysztof Wohlfeld, Eugene A. Demler +2
The problem of a mobile hole doped into an antiferromagnet Mott insulator is believed to underly the rich physics of several paradigmatic strongly correlated electron systems, rang…

Magnetic polarons due to spin-length fluctuations in spin-orbit Mott systems
Jan Revenda, Krzysztof Wohlfeld, JiÅÃ Chaloupka
Mott insulators based on and transition-metal ions, where spin-orbit interaction plays a key role, can exhibit various forms of unusual magnetism. A particular example is…
