论文摘要
我们通过实验表明，在准二维超材料中可能发生类似主要的结合状态（MLBS），类似于Kitaev链中的Majorana零模式（MZM）。在机械旋转器梯子系统中，我们观察到拓扑相变和光谱差距保护的边缘MLBS。我们表征了这些MLB对及其相关杂交的衰减和振荡性。结果表明，可以调节杂交以产生均方根转换的类似物，这是拓扑量子的关键要素。我们发现与理论达成了强有力的协议。
We experimentally demonstrate that Majorana-like bound states (MLBSs) can occur in quasi-one-dimensional metamaterials, analogous to Majorana zero modes (MZM) in the Kitaev chain. In a mechanical spinner ladder system, we observe a topological phase transition and spectral-gap-protected edge MLBSs. We characterize the decaying and oscillatory nature of these MLBS pairs and their phase-dependent hybridization. It is shown that the hybridization can be tuned to yield the analogue of parity switching in MZMs, a key element of topological qubits. We find strong agreements with theory.
