Heterostructuring as Gateway to Electron Doping of Nickelate Superconductors
Chao Deng, Motoharu Kitatani, Guiwen Jiang +7
Despite enormous expenditures in the research field, the electron-doped side of nickelate superconductors remains uncharted territory. Substituting the trivalent rare-earth cations…
First-principles calculation of coherence length and penetration depth based on density functional theory for superconductors
Mitsuaki Kawamura, Takuya Nomoto, Niklas Witt +1
We develop a first-principles framework for evaluating the fundamental length scales of superconductivity, namely the coherence length and the magnetic penetration depth $λ_\…
Superconductivity governed by Janus-faced fermiology in strained bilayer nickelates
Siheon Ryee, Niklas Witt, Giorgio Sangiovanni +1
High-temperature superconductivity in pressurized and strained bilayer nickelates (La,Pr)NiO has emerged as a new frontier. One of the key unresolved issues concerns th…
Quenched pair breaking by interlayer correlations as a key to superconductivity in LaNiO
Siheon Ryee, Niklas Witt, Tim O. Wehling
The recent discovery of superconductivity in LaNiO with under high pressure opens up a new route to high- superconduct…
No superconductivity in PbCu(PO)O found in orbital and spin fluctuation exchange calculations
Niklas Witt, Liang Si, Jan M. Tomczak +2
Finding a material that turns superconducting under ambient conditions has been the goal of over a century of research, and recently PbCu(PO)O aka LK-99 has be…
Doping fingerprints of spin and lattice fluctuations in moiré superlattice systems
Niklas Witt, José M. Pizarro, Jan Berges +3
Twisted Van der Waals systems offer the unprecedented possibility to tune different states of correlated quantum matter with an external non-invasive electrostatic doping. The natu…
