论文摘要
在约瑟夫森连接处预测并观察到了Bloch振荡，它们在薄薄的隔离或导电层桥接两个超导体。在这里，我们转发了一种利用这些振荡来放大纳米 - 金属机械振动的方案。可以通过简单地应用直流偏置电流和平面磁场来产生和控制高度相干的非经典机械状态。振动诱导连接的I-V特征峰，可以通过简单的直流电压测量来检测。
Bloch oscillations were predicted and observed long ago in Josephson junctions, which are thin insulating or conducting layers bridging two superconductors. Here we forward a scheme for utilizing these oscillations to amplify nano-metric mechanical vibrations. Highly coherent non-classical mechanical states can be produced and controlled by simply applying a DC bias current and an in-plane magnetic field. The vibrations induce peaks in the I-V characteristic of the junction and can be detected by simple DC voltage measurements.
