## Description

- description: 'We use resonant inelastic x-ray scattering (RIXS) at the O K- and
    Cu K-edges to investigate the doping- and temperature dependence of low-energy
    plasmon excitations in La2−xSrxCuO4. We observe a monotonic increase of the energy
    scale of the plasmons with increasing doping x in the underdoped regime, whereas
    a saturation occurs above optimal doping x>0.16 and persists at least up to x=0.4.
    Furthermore, we find that the plasmon excitations show only a marginal temperature
    dependence, and possible effects due to the superconducting transition and the
    onset of strange metal behavior are either absent or below the detection limit
    of our experiment. Taking into account the strongly correlated character of the
    cuprates, we show that layered t-J-V model calculations accurately capture the
    increase of the plasmon energy in the underdoped regime. '
