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.

我们对维格纳固体在液氦上的非线性输运进行了如下实验。1）液氦4表面上维格纳固体的等离子体共振为了研究维格纳固体和液体表面的动力学，我们进行了等离子体共振实验。在使用 Liquid He-4 的初步实验中，我们观察到了所谓的耦合等离子激元（CPR）模式。我们将研究超流He-3自由表面上维格纳固体的CPR共振。 3.2）超流氦3自由表面上维格纳固体的电导率测量我们制备了铜核退磁制冷机。超流He-3表面上维格纳固体的电导率测量正在进行中。
