Charge correlation, doublon-holon binding and screening in the doped Hubbard model
Edin Kapetanović, Guglielmo Nicola Gigante, Malte Schüler +2
Electronic correlations arise from the competition between the electrons' kinetic and Coulomb interaction energy and give rise to a rich phase diagram and many emergent quasipartic…
Downfolding from Ab Initio to Interacting Model Hamiltonians: Comprehensive Analysis and Benchmarking of the DFT+cRPA Approach
Yueqing Chang, Erik G. C. P. van Loon, Brandon Eskridge +8
Model Hamiltonians are regularly derived from first-principles data to describe correlated matter. However, the standard methods for this contain a number of largely unexplored app…
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…
Bypassing the lattice BCS-BEC crossover in strongly correlated superconductors: resilient coherence from multiorbital physics
Niklas Witt, Yusuke Nomura, Sergey Brener +3
Superconductivity emerges from the spatial coherence of a macroscopic condensate of Cooper pairs. Increasingly strong binding and localization of electrons into these pairs comprom…
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…
Unconventional charge-density-wave gap in monolayer NbS
Timo Knispel, Jan Berges, Arne Schobert +5
Using scanning tunneling microscopy and spectroscopy, for a monolayer of transition metal dichalcogenide H-NbS grown by molecular beam epitaxy on graphene, we provide unambiguo…
