Abstract

We report an observation of a dynamical transition in the Wigner solid on liquid 4He. The AC conductivity σxx jumps abruptly at a certain input voltage. The threshold input voltage Vth for the σxx jump varies as Vth∝B-0.8f-1n1.5 sE, where B, f, ns, and E are magnetic field, frequency, electron density and pressing electric field, respectively. We interpret the σxx jump as the collective sliding of the electrons out of the periodic deformation of the He surface.
