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 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…

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…
