Abstract
The spectrum of coupled electron-ripplon oscillations in a Wigner crystal was experimentally studied as a function of the amplitude of the excitation signal. It was found that an increase in the excitation voltage leads to a noticeable distortion of the spectrum and a shift in the resonance characteristics to the region of lower frequencies. Analysis of the spectra demonstrated that non-axially symmetric oscillations are excited in the cell. In view of the radial symmetry of the cell and the exciting electrode, excitation of such oscillations may be attributed to the distortion of the crystal lattice. In the analysis, it was assumed that the electron-ripplon interaction leads only to a renormalization of the effective mass of the electrons.
