We find that this material is a low carrier density metal with a moderate level of correlations and exhibits signatures of electron-boson coupling. The data is consistent with the presence of coherent quasiparticles in LaFePO.","authors_text":"D. N. Basov, J. J. Hamlin, M. B. Maple, M. M. Qazilbash, R. E.
