Experimental activities and responsibilities

Responsible of:

  •  low losses Faraday Isolators (FIs)in air and in vacuum for the injection of the frequency dependent squeezing (FDS) in Advanced Virgo+ for next observing run O4
  • optical design and assembly of the homodyne detector for FDS at Virgo
  • optomechanical design of SIPS (Suspended Interferometer for Ponderomotive Squeezing). Experiment aiming at reducing quantum noise in the detection band of ground- based GW detectors
    Work published: Eur. Phys. J. D (2020) 74: 227
    DOI: 10.1140/epjd/e2020-10183-7
  • optical design of EPR squeezer for Advanced Virgo (co-responsible). Project funded by INFN for the realisation of a squeezer based on quantum entanglement (Einstein Podolsky Rosen) principle for broadband quantum noise reduction in Virgo.
  • optical design integration of SIPS and EPR squeezer for Advanced Virgo. Work presented at GW science and technology Symposium (GRASS) 2019 and published on Zenodo (2020) DOI: 10.5281/zenodo.3569196. The integration of EPR with SIPS will allow to test broadband quantum noise reduction in a suspended table-top interferometer before possible application on large scale interferometers such as Advanced Virgo.
