We consider the instability of a two-dimensional Wigner crystal in a short-period lateral superlattice. To find instabilities, we calculate the phonon spectrum of the electron lattice deformed by a periodic potential. We show that one of the transverse modes of the deformed electron crystal becomes

We derive an effective potential for a two-dimensional Wigner crystal that not only leads to the correct partition function but also describes the dynamical properties of the system accurately in the low temperature and the strong magnetic field limits.
