Abstract

A different formalism is proposed to derive the magnetoplasmon
dispersion curves of a two-dimensional electron gas in strong
magnetic fields for arbitrary values of the filling factor and
in presence of band nonparabolicity effects. These effects are
found to be responsible for pronounced nonlinear magnetoplasmon
dispersion associated with spectacular changes in the infrared
activity of these modes.
