摘要

电磁谐振系统,如空腔和LC电路,被广泛用于探测超轻玻色子暗物质和高频引力波。然而,单模谐振器的窄带宽需要多个扫描步骤来覆盖较宽的频率范围。通过通过分束器和非简并参数耦合整合辅助模式网络,我们实现了宽带检测,每次扫描的有效带宽与谐振频率的顺序相匹配,同时保持了强信号响应。在外差上转换检测中,由于潜在的背景源,背景腔模式转变为另一种模式,可以在不调整腔频率的情况下以高灵敏度探测源频率的多个阶。因此,与单模检测相比,我们的方法允许在相同的积分时间内对参数空间进行更深入的探索。

Simultaneous Resonant and Broadband Detection of Ultralight Dark Matter and High-Frequency Gravitational Waves via Cavities and Circuits.
Electromagnetic resonant systems, such as cavities and LC circuits, are widely used to detect ultralight boson dark matter and high-frequency gravitational waves. However, the narrow bandwidth of single-mode resonators necessitates multiple scan steps to cover broad frequency ranges. By incorporating a network of auxiliary modes via beam-splitter-type and non-degenerate parametric couplings, we enable broadband detection with an effective bandwidth of each scan matching the order of the resonant frequency, while maintaining a strong signal response. In heterodyne upconversion detection, where a background cavity mode transitions into another due to a potential background source, multiple orders of the source frequency can be probed with high sensitivity without tuning the cavity frequency. Consequently, our method allows for significantly deeper exploration of the parameter space within the same integration time compared to single-mode detection.
