Renormalization of electronic structure close to Fermi level of CeIrIn$_{5}$ at 20K

ORAL

Abstract

The electronic structure of heavy-fermion superconductor CeIrIn$_{5}$ is investigated at $\sim $20K by high-resolution angle-resolved photoemission (ARPES). The low energy ARPES spectra indicate a kink near the Fermi surface within the~energy scale of~the order of~20meV.~Existence of a kink may suggest~coupling of electron~to~a collective boson mode of unknown origin.
