DESCRIPTION:Speakers: Valentina Danieli (CEICO\, Prague)\n\nMagnetically l
 evitated superconductors provide a promising platform for detecting ultra-
 light dark matter through precision force measurements. In this talk\, I w
 ill discuss our study of spin-2 dark matter—the dark graviton—and its 
 effects on such systems via both matter and electromagnetic couplings. The
  former induces a tidal\, strain-like force similar to a continuous gravit
 ational wave\, while the latter generates an effective current that produc
 es an oscillating magnetic field. We model the system as a driven harmonic
  oscillator and derive the expected signals across the dHz–kHz frequency
  range. Our projections show that future detectors could surpass existing 
 bounds on matter couplings in the audio band and explore previously uncons
 trained photon couplings at low frequencies. With significant experimental
  advances and careful control of technical and readout noise\, magneticall
 y levitated superconductors could therefore become leading laboratory prob
 es of dark graviton interactions.\n\nhttps://indico.ifae.es/event/2718/
