Low-frequency conductivity of a two-dimensional Wigner solid coupled to surface excitations of liquid helium
The line-shape and broadening of coupled phonon-ripplon resonances of Wigner-solid conductivity are studied using the memory function formalism. The analytic properties of the memory function permit coordinating the approximations of the secular equation for the coupled phonon-ripplon modes and the...
