尽管质量高于\(10^{-4}\,\mathrm{eV}\)的隐藏光子暗物质因暴胀产生而备受关注，但地面实验对此探索甚少。通过动力学混合，隐藏光子会在\(10\,\mathrm{GHz}\)以上感应出微弱振荡电场。我们提议用紧凑型高频分布式腔放大该信号，并采用芯片级里德堡原子超外差光谱法进行探测。此方法结合共振增强、里德堡原子的大偶极矩和长期稳定积分，能探测质量范围在\(5 \times 10^{-5}\text{--}7\times 10^{-4}\,\mathrm{eV}\)的隐藏光子暗物质，灵敏度比现有极限高出\(3\)至\(4\)个数量级。
英文摘要
Although hidden-photon dark matter with masses above $10^{-4}\,\mathrm{eV}$ is well motivated by inflationary production, it remains largely unexplored by terrestrial experiments. Through kinetic mixing, hidden photons induce a weak oscillating electric field above $10\,\mathrm{GHz}$. We propose to amplify this signal using a compact high-frequency distributed cavity and detect it with chip-scale Rydberg-atom superheterodyne spectroscopy. Combining resonant enhancement, large dipole moments of Rydberg atoms, and long-term stable integration, this approach can probe hidden-photon dark matter in the mass range $5 \times 10^{-5}\text{--}7\times 10^{-4}\,\mathrm{eV}$ with sensitivities $3$--$4$ orders of magnitude beyond existing limits.
