Abstract
We have performed ultrahigh-resolution angle-resolved photoemission spectroscopy (ARPES) to elucidate the nature of quasiparticle dynamics in graphite. We found fairly sharp quasiparticle peak of π band around K(H) point in the vicinity of the Fermi level, together with the strong mass renormalization of the band (kink). The imaginary part of electron self-energy (ImΣ) shows a sudden drop below 0.18 eV, indicative of a strong electron-phonon coupling. The linear energy dependence of ImΣ at higher binding energies provides an evidence for the deviation from the conventional Fermi liquid theory.
