Query: Sliding Dynamics of the Wigner Crystal on Liquid He   The Wigner crystal on liquid He accompanies with periodic corrugation of the
He surface; dimples. The dynamics of the crystal is coupled with the motion and
the deformation of the dimples. Nonlinear phenomena found in AC Corbino
conductivity are attributed to the collective sliding of the electrons out of
the dimples. In order to inspect the dynamical transition to the sliding state,
we have developed a novel experimental method using a so-called "t^2 pulse",
whose leading and trailing edges change in proportion to the square of time; V
= at^2. Since the force exerting upon the crystal is proportional to the time
derivative of the input voltage, dV/dt, the t^2-pulsed method is expected to
realize a continuous sweep of the driving force, resulting in the real-time
observation of the sliding transition. The observed response shows clearly the
sliding, revealing that the external force to the crystal determines the
sliding transition.
