## Description

- description: Charge excitation spectra are getting clear in cuprate superconductors
    in momentum-energy space especially around a small momentum region, where plasmon
    excitations become dominant. Here, we study whether Landau quasiparticles survive
    in the presence of charge fluctuations observed in experiments. We employ the
    layered t -J model with the long-range Coulomb interaction, which can reproduce
    the realistic charge fluctuations. We find that Landau quasiparticles are retained
    in a realistic temperature and doping region, although the quasiparticle spectral
    weight is strongly reduced to 0.08–0.24. Counterintuitively, the presence of this
    small quasiparticle weight does not work favorably to generate a pseudogap.
