Frequency spectrum of surface plasmon-polariton waves: influence of Coulomb correlations

The model that describes the influence of Coulomb interaction between electrons (Coulomb correlations) on a frequency spectrum of plasmon-polariton waves in electroneutral structures dielectric/metal/dielectric is investigated.  It is shown that for atomically thin metal films (ATMF), such correlations affects both the quantum-dimensional behavior of the frequency spectrum as a function of the thickness of the metal film and
significantly improves the correlation of theoretical calculations and experiment.
