Dark graviton sensing with magnetically levitated superconductors
Valentina Danieli, Paola C. M. Delgado, Federico R. Urban
Levitated sensors have emerged as a new frontier to detect ultra-light dark matter such as axion-like particles and dark photons. In this work we study how a magnetically levitated…

Anharmonic Effects on the Squeezing of Axion Perturbations
Valentina Danieli, Takeshi Kobayashi, Nicola Bartolo +2
It is assumed in standard cosmology that the Universe underwent a period of inflation in its earliest phase, providing the seeds for structure formation through vacuum fluctuations…
