Revealing the Electron-Spin Fluctuation Coupling by Photoemission in CaKFe_{4}As_{4}
Electron-boson coupling in unconventional superconductors is one of the key parameters in understanding the superconducting pairing symmetry. Here, we report definitive photoemission evidence of electron-spin fluctuation coupling in the iron-based superconductor CaKFe_{4}As_{4}, obtained via high-re...
