Abstract
Here we study the collective excitations of a dilute spin-polarized Bose-Fermi mixture at zero temperature, considering, in particular, the features arising from the interaction between the two species. We show that a propagating zero-sound mode is possible for the fermions even when they do not interact among themselves.Keywords
