Lowfrequency electromagnetic field in a Wigner crystal
Abstract
Longwave lowfrequency oscillations are described in a Wigner crystal by generalization of the reverse continuum model for the case of electronic lattice. The internal selfconsistent longwave electromagnetic field is used to describe the collective motions in the system. The eigenvectors and eigenvalues of the obtained system of equations are derived. The velocities of longitudinal and transversal sound waves are found.
