Electron-plasmon interaction in a thin cylindrical wire is described in terms of four-dimensional Kaluza-Klein theory in which angular coordinate of the metal cylinder is considered to be one of the two compactified coordinates. In this model electron-electron, electron-plasmon and nonlinear optical plasmon-plasmon interactions are unified via introduction of effective superchiral charges and fields. Such an approach has important consequences for description of electromagnetic and transport properties of mesoscopic metallic wires and rings at low temperatures, such as recent observation of density-dependent spin polarization in quantum wires. This theory may be consistently reformulated using normal language of classical physics as nonlinear electrodynamics of a rotating medium.
