Abstract
The spectra of magnetoplasma waves, zero sound and spin waves in an electron gas on a surface of a nonferromagnetic nanotube in longitudinal magnetic field are considered. The initial spectrum of the electron energy is assumed to be parabolic, and the interelectron interaction is taken into account within the random-phase approximation. It is shown that in a magnetic field there is a shift of the frequency of an intersubband plasmon proportional to a magnetic flux through a cross-section of a tube. The frequency and the damping constant of magnetoplasma waves in a nondegenerate electron gas are calculated. For a great number of filled subbands the frequencies of the zero sound and spin waves in a degenerate electron gas experience oscillations of the type of de Haas-van Alphen and Aharonov-Bohm with changing the density of electrons and magnetic flux.
