While the long-range Coulomb interaction (~1/r) is usually handled in a continuum space, I here provide its function form on a bilayer lattice system and elucidate the resulting charge dynamics. The results are compared with resonant inelastic x-ray scattering data obtained in Y-based high-temperature cuprate superconductors with Tc close to 100 K.
