报告摘要:Ultralight bosons behave like coherent waves when the occupation number is large enough. Such an oscillating background can induce a tiny signal to the visible sector. Resonant detection of axion dark matter based on electromagnetic coupling is a popular direction attracting many ongoing experiments and proposals such as microwave cavity, LC circuit and superconducting radio-frequency cavity. A multi-resonator system with PT symmetry can strongly enhance the signal power and boost the search. On the other hand, a network of spin dependent sensors with long baseline can identity the microscopic nature of dark matter or other cosmological background and increase the spatial resolution for transient source like axion or dark photon wave from the superradiant black hole as well.
