Abstract
We present a simple analytical method to compute the approximate spectrum of elementary collective excitations for hypothetical arbitrarily many-component ‘‘electron-hole’’ fluids. Numerical results are given for two- and ten-component systems in three dimensions and for a six-component system in two dimensions.Keywords
