Abstract

We have studied strongly nonlinear transport phenomena in the Wigner solid (WS) on liquid 4He. The Corbino conductivity σxx exhibited an abrupt jump, which separates two states of the WS; in one state the WS is registered in the surface deformation, whereas in the other state the WS is decoupled from the deformation. The boundary between these two states is empirically described in terms of the input voltage Vin, the magnetic field B perpendicular to the surface, measuring frequency ω, electron density ns, and pressing electric field E as Vinωns-1.5B0.8E -1∼constant. This empirical relation is derived from a model to describe the collective sliding of the electrons out of the periodic deformation of the He surface. Anomalous behaviors of the conductivity of the WS are crucial to interpret the phenomenon.
