报告摘要：
In the vicinity of black holes, particle density can significantly increase, acting as efficient transducers. This is evident in the superradiant generation of ultralight bosons, which can attain Planck-scale field values. Within this dense boson environment, we witness the occurrence of non-perturbative particle production—a phenomenon previously associated primarily with the early-universe cosmology. This talk will explore their impact on various observational channels associated with black holes, such as the high-energy neutrino observatories and Event Horizon Telescope. On the other hand, quantum sensing stands at the forefront of fundamental physics measurements, poised to significantly advance our comprehension of the universe. This talk will discuss recent experimental advancement in the utilization of a superconducting radio frequency cavity for the detection of dark photon dark matter and galactic dark photons. Furthermore, it delves into the future potential of these detectors in probing dark sectors, emphasizing innovative upgrades that can simultaneously operate as resonant and broadband instruments.
