| Towards Dark Matter Searches using Levitated Superconductors |
| Speaker: | Gerard Higgins (IQOQI Wien) |
| Abstract: | Magnetically-levitated superconductors can serve as ultrasensitive mechanical sensors: The motion of levitated superconductors can be precisely measured using superconducting quantum circuits [1-3], offering the potential for sensing beyond the standard quantum limit. These systems can be operated in low noise environments [1], within ultrahigh vacuum, at cryogenic temperatures, and using near-dissipationless traps. Whatâs more, sizable superconducting masses can be levitated [4], allowing these systems to be scaled-up, to create record-breaking acceleration sensors for probing new physics.
I plan to build levitated superconductor sensors, and I will use them to hunt for a range of dark matter candidates in the laboratory [5]. Enticingly, levitated superconductors have the potential to probe the existence of dark matter via its gravitational interaction with ordinary matter [6]. This app |
