- 요약The particle nature of dark matter is one of the major open problems in fundamental physics. This dissertation explores novel detection methods for various dark matter candidates, bringing techniques from atomic physics and neutrino physics into dark matter searches.Ultralight dark matter in the meV mass range is notoriously difficult to detect, being too high in frequency for high-Q cavity resonators yet below the energy threshold of single-photon detectors. We propose using highly excited cyclotron states of a trapped electron to detect meV axion and dark photon dark matter. When the dark matter mass matches the cyclotron frequency, the cyclotron state is resonantly excited, with a transition probability proportional to its initial quantum number. By optimizing key experimental parameters, we minimize the required averaging time for cyclotron detection, permitting detection of a highly excited state before its decay. An open-endcap trap design enables the external photon signal to be directed into the trap, rendering our background-free detector compatible with large focusing cavities, such as the BREAD proposal. These and other optimizations enable us to probe the QCD-axion parameter space in the meV range.Inelastic dark matter, such as the Higgsino, with large mass splittings evades conventional WIMP direct detection but can produce distinctive photon signals in large neutrino detectors like JUNO, following upscattering in the Earth and subsequent decay. We show that an enhanced high-velocity tail of the dark matter distribution due to the Large Magellanic Cloud improves the sensitivity of this method, and that adding a large volume of heavy elements, such as lead or uranium, around the detector could further take advantage of this effect.
