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.
  • R&D studies for the generation of Frequency Independent Squeezing for Virgo. Work published on Rev. Sci. Instrum., Vol. 92, 054504 (2021) DOI: 10.1063/5.0046317

nov. 2019: Visiting Researcher at Massachusetts Institute of Technology and collaboration with MIT-LIGO team for an experiment for the direct measurement of the thermal noise of mirror coatings, to study a strategy to improve coating thermal noise of GW ground-based detectors.

2018: R&D Studies on the Straylight for the future space mission LISA (Laser Interferometer Space Antenna, space-based GW detector to be launched in 2034). Work presented at the international conference NANOP 2018 and published on Open Mater. Sci. 2019; 5:12-18 (2019) DOI: 10.1515/oms-2019-0002
