Fermion–boson many-body interplay in a frustrated kagome paramagnet

Fermion–boson many-body interplay in a frustrated kagome paramagnet

Frustrated kagome magnets host both fermionic and bosonic excitations, but evidence of their interplay has been elusive. Here, the authors report a pronounced renormalization of electron bands near the Fermi surface due to the coupling with a flat phonon band in a kagome paramagnet, CoSn.
