Revealing the electron-spin fluctuation coupling by photoemission in CaKFe4As4
Peng Li, Yuzhe Wang, Yabin Liu +8
Electron-boson coupling in unconventional superconductors is one of the key parameters in understanding the superconducting pairing symmetry. Here, we report definitive photoemissi…

Evidence of electron interaction with an unidentified bosonic mode in superconductor CsCaFeAsF
Peng Li, Sen Liao, Zhicheng Wang +16
The kink structure in band dispersion usually refers to a certain electron-boson interaction, which is crucial in understanding the pairing in unconventional superconductors. Here…
