Abstract

Electron-phonon coupling is thought to be too weak to be responsible for the superconducting Cooper pairing of the kagome metals AV3Sb5, but an experimental measurement is lacking. Here, the authors use ARPES measurements to find that electron-phonon coupling in CsV3Sb5 is strong enough to support the experimental superconducting transition.
