Femtosecond concerted rotation of molecules on a 2D material interface
Kiana Baumgärtner, Misa Nozaki, Marvin Reuner +20
Interfaces between molecules and 2D materials exhibit energy-driven functionalities, wherein charge transfer directs molecular motion. Unlike equilibrium systems, where molecular a…
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…
Charge correlation, doublon-holon binding and screening in the doped Hubbard model
Edin KapetanoviÄ, 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…
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…
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…
