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…

Analysis methodology of coherent oscillations in time- and angle-resolved photoemission spectroscopy
Nicolas Gauthier, Hadas Soifer, Jonathan A. Sobota +5
Oscillatory signals from coherently excited phonons are regularly observed in ultrafast pump-probe experiments on condensed matter samples. Electron-phonon coupling implies that co…

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…
