Closing in on possible scenarios for infinite-layer nickelates: comparison of dynamical mean-field theory with angular-resolved photoemission spectroscopy

Liang Si, Eric Jacob, Wenfeng Wu +6

Conflicting theoretical scenarios for infinite-layer nickelate superconductors have been hotly debated, particularly regarding whether {only} a single Ni-3 band is rel…

Spin fluctuations sufficient to mediate superconductivity in nickelates

Paul Worm, Qisi Wang, Motoharu Kitatani +12

Infinite-layer nickelates show high-temperature superconductivity, and the experimental phase diagram agrees well with the one simulated within the dynamical vertex approximation (…

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…

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.…

Optimizing superconductivity: from cuprates via nickelates to palladates

Motoharu Kitatani, Liang Si, Paul Worm +3

Motivated by cuprate and nickelate superconductors, we perform a comprehensive study of the superconducting instability in the single-band Hubbard model. We calculate the spectrum…

Signatures of topotactic hydrogen in nickelate superconductors

Liang Si, Paul Worm, Karsten Held

Superconductivity has entered the nickel age marked by enormous experimental and theoretical efforts. Notwithstanding, synthesizing nickelate superconductors remains extremely chal…

Phase diagram of nickelate superconductors calculated by dynamical vertex approximation

Karsten Held, Liang Si, Paul Worm +5

We review the electronic structure of nickelate superconductors with and without effects of electronic correlations. As a minimal model we identify the one-band Hubbard model for t…

Correlations turn electronic structure of finite-layer nickelates upside down

Paul Worm, Liang Si, Motoharu Kitatani +3

Motivated by the recent discovery of superconductivity in the pentalayer nickelate NdNiO [Nature Materials 10.1038], we calculate its electronic structure and superc…

Hidden, one-dimensional, strongly nested, and almost half-filled Fermi surface in BaCuO superconductors

Paul Worm, Motoharu Kitatani, Jan M. Tomczak +2

All previous cuprate superconductors display a set of common features: (i) vicinity to a Cu 3 configuration; (ii) separated CuO planes; (iii) superconductivity for dopin…
