摘要:

我们提出了扫描光学频闪共焦显微镜和光谱测量,其中三个自由度,即能量,实时空间和实时,是可分辨的。边缘状态传播被检测为下游边缘中的光学响应的时间变化。我们成功地观察到了最基本的分数量子霍尔(FractionalQuantumHall,HALL)态的激发态和边缘附近的集体激发。结果验证了目前的理解的边缘激励,也指向边缘通道外的进一步动态。

英文摘要:

We present scanning optical stroboscopic confocal microscopy and spectroscopy measurements wherein three degrees of freedom, namely energy, real-space, and real-time, are resolvable. The edge-state propagation is detected as a temporal change in the optical response in the downstream edge. We succeeded in visualizing the excited states of the most fundamental fractional quantum Hall (FQH) state and the collective excitations near the edge. The results verify the current understanding of the edge excitation and also point toward further dynamics outside the edge channel.
