Nodal Landau Fermi-liquid quasiparticles in overdoped La1.77Sr0.23CuO4
Abstract : Nodal angle-resolved photoemission spectra taken on overdoped La 1.77 Sr 0.23 CuO 4 are presented and analyzed. It is proven that the low-energy excitations are true Landau Fermi-liquid quasiparticles. We show that momentum and energy distribution curves can be analyzed self-consistently without quantitative knowledge of the bare band dispersion. Finally, by imposing Kramers-Kronig consistency on the self-energy , insight into the quasiparticle residue is gained. We conclude by comparing our results to quasiparticle properties extracted from thermodynamic, magnetoresistance, and high-field quantum oscillation experiments on overdoped Tl 2 Ba 2 CuO 6+δ .
