论文摘要
我们研究参数振荡器阵列中拓扑扩增的现象。我们发现拓扑扩增的两个阶段，包括定向运输和指数增益，其中一个地点数量，其中一个带有挤压。我们还发现了一个具有零能量模式的拓扑阶段，它会产生放大，但缺乏对其他人的强大拓扑保护。我们表征了对不同阶段及其稳定性，稳定性，增益和信号比率的韧性。最后，我们通过最先进的技术讨论了他们的实验实施。
We study the phenomena of topological amplification in arrays of parametric oscillators. We find two phases of topological amplification, both with directional transport and exponential gain with the number of sites, and one of them featuring squeezing. We also find a topologically trivial phase with zero-energy modes which produces amplification but lacks the robust topological protection of the others. We characterize the resilience to disorder of the different phases and their stability, gain, and noise-to-signal ratio. Finally, we discuss their experimental implementation with state-of-the-art techniques.
