Unconventional superconductivity without doping: infinite-layer nickelates under pressure
Simone Di Cataldo, Paul Worm, Jan Tomczak +2
High-temperature unconventional superconductivity quite generically emerges from doping a strongly correlated parent compound, often (close to) an antiferromagnetic insulator. The…
A possible explanation for the high superconducting Tc in bcc Ti at high pressure
Antonio Sanna, Camilla Pellegrini, Simone di Cataldo +2
Motivated by unexpected reports of a 26 K superconducting transition in elemental titanium at high pressure, we carry out an accurate ab-initio study of its properties to understan…
PbCu(PO)O: a Mott or charge transfer insulator in need of further doping for (super)conductivity
Liang Si, Markus Wallerberger, Andriy Smolyanyuk +3
We briefly review the status quo of research on the putative superconductor PbCu(PO)O also known as LK-99. Further, we provide {\em ab initio} derived tight-binding par…
Phase diagram and superconductivity of Calcium Alanates under pressure
Simone Di Cataldo, Lilia Boeri
In this paper we present a first-principles study of the high-pressure superconducting phase diagram of calcium alanates (Ca-Al-H), based on ab-initio crystal structure prediction…
Absence of electron-phonon-mediated superconductivity in hydrogen-intercalated nickelates
Simone Di Cataldo, Paul Worm, Liang Si +1
A recent experiment [X. Ding et al., Nature 615, 50 (2023)] indicates that superconductivity in nickelates is restricted to a narrow window of hydrogen concentration: 0.22 < x < 0.…
Search for ambient superconductivity in the Lu-N-H system
Pedro P. Ferreira, Lewis J. Conway, Alessio Cucciari +7
Motivated by the recent report of room-temperature superconductivity at near-ambient pressure in N-doped lutetium hydride by Dasenbrock et al. [Nature 615, 244 (2023)], we performe…
