论文摘要
我们提出了扫描光学频道共聚焦显微镜和光谱测量值，其中三个自由度，即能量，真实空间和实时。在下游边缘中检测到边缘状态传播是光学响应的时间变化。我们成功地想象了最基本的分数量子厅（FQH）的激发态和边缘附近的集体激发。结果验证了对边缘激发的当前理解，还指向边缘通道之外的进一步动态。
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.
