Descripción
Recent calculations have demonstrated that we may attempt the direct detection of dark matter in the laboratory through gravitational interaction alone. This is in particular relevant around the well-motivated Planck mass scale (10^19 GeV or 22 micro-gram). The Windchime collaboration is working towards a large array of dedicated sensors, based on MEMS accelerometers. Paired with quantum-enhanced readout including squeezed light sources and quantum back-action evasion, such an experiment may ultimately realize this exciting sensitivity. In the meantime, searches for ultra-light (<10^-10 eV) dark matter candidates provide an interesting application of our detector prototypes. In this talk, I will present the idea of Windchime, our prototype setups, as well as recent developments of sensors, quantum readout, simulations, and analysis frameworks.
