Abstract
Anyon superfluidity is studied by using nonrelativistic currents and d ensities as coordinates. The excitation spectrum, obtained by solving the equation of motion of a suitably constructed excitation operator, reveals the importance of vortex-type excitations and predicts an anom alous phonon dispersion in the long-wavelength limit.
