Macroscopic and mesoscopic ferromagnets levitated by Meissner effect in vacuum behave as multimode mechanical systems with ultrahigh quality factor and high sensitivity to external magnetic fields. Furthermore, they can be easily coupled to superconducting quantum devices. This suggests the possibility of using this experimental platform for a variety of measurements in the context of...
There is vast parameter space to explore for dark matter masses below a few GeV, and the field of direct dark matter detection is constantly expanding to new frontiers. In particular, low mass dark matter candidates necessitate novel detector designs with lower thresholds and alternative target materials compared to e.g. the xenon-based experiments currently providing the strongest overall...
