Propagation of electromagnetic waves in the electron Fermi liquid of a quasi-two-dimensional conductor under strong spatial dispersion

Abstract

We have analyzed propagation of electromagnetic waves in a Fermi liquid of charge carriers in quasi-two-dimensional layered conductors placed in a magnetic field. It is shown that high-frequency collective modes, which are absent in a gas of charge carriers, can be observed even at low intensity of the Fermi-liquid interaction. The spectrum of the weakly damping waves has been obtained.
