Abstract
A self-consistent theory of the admittance of a perfect ballistic,locally charge neutral wire is proposed. Compared to a non-interactingtheory, screening effects drastically change the frequency behavior ofthe conductance. In the single-channel case the frequency dependenceof the admittance is monotonic, while for two or more channelscollective interchannel excitations lead to resonant structures in theadmittance. The imaginary part of the admittance is typicallypositive, but can become negative near resonances.
