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…
