论文摘要

在这里,我们提出了一个新的引力波(GWS)检测器,该检测器在宽频带中,该检测器在微腔中的特殊点(EPS)进行。检测到的信号是由空间应变引起的机械模式的特征频率分裂。由于EP附近复杂的平方根拓扑,因此分裂大大增强了足够小的扰动。与当前的策略相比,它可以在室温下实现,并且具有微型设备尺度,频带和更高灵敏度的优点。

Here we propose a new gravitational waves(GWs) detector in broad frequency band, which is operated at exceptional points(EPs) in micro cavities. The detected signal is an eigenfrequency split of the mechanical modes caused by the spatial strain. Due to the complex square root topology near the EP, the splitting is greatly enhanced for sufficiently small perturbations. Compared to current strategies, it can be achieved at the room temperature and has advantages in micro device scale, wide frequency band and higher sensitivity.
