We have performed following experiments on the nonlinear transport of the Wigner solid on liquid Helium.1) Plasmon Resonance of the Wigner Solid on a Liquid Helium 4 SurfaceIn order to study the dynamics of the Wigner solid and the liquid surface, we have performed an experiment of the plasma resonance. In the preliminary experiment using Liquid He-4, we have observed so-called coupled plasmon-ripplon (CPR) modes. We will study the CPR resonance in the Wigner solid on the free surface of superfluid He-3.2) Conductivity Measurement of the Wigner Solid on the Free Surface of Superfluid Helium 3We have prepared a copper nuclear demagnetization refrigerator.Measurements of conductivity of the Wigner solid on a superfluid He-3 surface are underway.

我们已经在液体氦上进行了Wigner固体非线性转运的实验。1）Wigner固体在液体氦气4表面序列上的等离子体共振，以研究Wigner固体和液体表面的动力学，我们进行了等离子共振的实验。在使用液体HE-4的初步实验中，我们观察到了所谓的等离子 - 含量（CPR）模式。我们将研究超氟He-3.2的Wigner固体中的CPR共振。
