论文摘要
氦表面上的电子显示尖锐的谐振吸收线与横向量化运动的子带之间的过渡有关。平行于表面的磁场强烈影响吸收光谱。我们表明，效果来自将平面外运动混合到强相关的电子液体或wigner晶体的平面量子动力学。这类似于彩色中心向声子中的混合电子过渡。该频谱允许直接表征多电子动力学，还可以在具有可控耦合的系统中测试颜色中心的理论。
Electrons on the helium surface display sharp resonant absorption lines related to the transitions between the subbands of quantized motion transverse to the surface. A magnetic field parallel to the surface strongly affects the absorption spectrum. We show that the effect comes from admixing the out-of-plane motion to the in-plane quantum dynamics of the strongly correlated electron liquid or a Wigner crystal. This is similar to the admixing electron transitions in color centers to phonons. The spectrum permits a direct characterization of the many-electron dynamics and also enables testing the theory of color centers in a system with a controllable coupling.
