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…
Spin and Charge Fluctuation Induced Pairing in ABCB Tetralayer Graphene
Ammon Fischer, Lennart Klebl, Jonas B. Profe +5
Motivated by the recent experimental realization of ABCB stacked tetralayer graphene [Wirth et al., ACS Nano 16, 16617 (2022)], we study correlated phenomena in moiré-less graphene…
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…
Interplay of screening and superconductivity in low-dimensional materials
G. Schönhoff, M. Rösner, R. Groenewald +2
A quantitative description of Coulomb interactions is developed for two-dimensional superconducting materials, enabling us to compare intrinsic with external screening effects, suc…
