论文摘要
使用在变形的蜂窝晶格中排列的一系列耦合的微波谐振器，我们通过实验观察到从消失到大型磁磁场强度的整个交叉中的伪landau水平的形成。这是通过在几何形状中利用与伪landau水平兼容的几何形状中的适应性设置来实现的。采用的方法使人们能够在状态的光子密度中观察到完全形成的平板伪landau水平，并在空间上对相关的波函数进行图像，在其中我们提供了明确的证据，证明了反映了以前难以捉摸的低层理论中先前难以捉摸的超对称性。特别是，我们解决了异常的0个伪landau水平的完整sublattice极化，在未经培训的情况下，它揭示了与Zigzag边缘状态的密切联系。
Using an array of coupled microwave resonators arranged in a deformed honeycomb lattice, we experimentally observe the formation of pseudo-Landau levels in the whole crossover from vanishing to large pseudomagnetic field strength. This is achieved by utilizing an adaptable set-up in a geometry that is compatible with the pseudo-Landau levels at all field strengths. The adopted approach enables to observe fully formed flat-band pseudo-Landau levels spectrally as sharp peaks in the photonic density of states, and image the associated wavefunctions spatially, where we provide clear evidence for a characteristic nodal structure reflecting the previously elusive supersymmetry in the underlying low-energy theory. In particular, we resolve the full sublattice polarization of the anomalous 0th pseudo-Landau level, which reveals a deep connection to zigzag edge states in the unstrained case.
