Observation of Two Cascading Screening Processes in an Iron-based Superconductor
Ming-Hua Chang, Steffen Backes, Donghui Lu +8
Understanding how renormalized quasiparticles emerge in strongly correlated electron materials provides a challenge for both experiment and theory. It has been predicted that disti…

Altermagnetism on the Shastry-Sutherland lattice
Francesco Ferrari, Roser Valenti
Motivated by recent developments on altermagnetism, we investigate the Hubbard model on the Shastry-Sutherland lattice, where the onsite repulsion between electrons induces the ons…

Dispersion kinks from electronic correlations in an unconventional iron-based superconductor
Ming-Hua Chang, Steffen Backes, Donghui Lu +7
The attractive interaction in conventional BCS superconductors is provided by a bosonic mode. However, the pairing glue of most unconventional superconductors is unknown. The effec…
