Dark matter (DM) comprises approximately 27% of the energy in the observable universe. Its properties, such as its mass and interactions, remain largely unknown. Unveiling the properties of DM is one of the most important tasks in high energy physics. For the past few years, motivated by possible new physics at the electroweak scale, many DM experiments have looked for DM with mass at O(100) GeV. This is not the only possibility, however. Large chunks of parameter space supported by other well-motivated models remain to be carefully studied. Exploring these regimes requires creative ideas and advanced technologies. I will first talk about the novel proposal on using superconductor as the target material for DM direct detection. This setup has the potential to lower the direct detection mass threshold from few GeV to keV, consequently probing the warm dark matter scenario. Then I will present a recent proposal utilizing the Gravitational Wave (GW) experiments, i.e. LIGO and LISA, to search for ultra-light dark photon dark matter. We show these GW experiments can go well beyond existing constraints and probe large regions of unexplored parameter space. Both proposals are under serious investigation by experimental groups and likely to be carried out in the near future.
