We use O K-edge resonant inelastic x-ray scattering to reveal plasmon excitations in the optimally doped trilayer Bi2Sr2Ca2Cu3O10+delta. The observed plasmon exhibits nearly qz-independent dispersion and a large excitation gap of approximately 300 meV. This mode is primarily ascribed to the omega− mode, where the charge density on the outer CuO2 sheets oscillates out of phase while the density in the inner sheet remains unaltered at qz = 0. The intensity of the acoustic omega3 mode is relatively weak and becomes vanishingly small near (qx , qy ) = (0, 0). This result highlights a qualitative change in the eigenmode of the dominant low-energy plasmon with the number of CuO2 layers. description_type: abstract lang: und ## Creator - name: S.
