Gravitational-wave astronomy began its remarkable legacy on September 14th, 2015, with the ground-breaking detection of a GW signal produced by the coalescence of two black holes. The exciting outcomes from this young research field range from cosmology and multimessenger astrophysics to fundamental physics. The current GW detectors are broadband (10 - 10000 Hz) Michelson interferometers that...
Answering the most puzzling questions in fundamental physis drives a continuous quest for the development of new detection techniques allowing to go beyond traditional measurement approaches. On this purpose, an increasing R&D activity for the development of new detection strategies based on exploiting the extreme sensitivity of quantum systems is currently ongoing, aiming at introducing...
This work proposes a novel architecture that utilizes recent advancements in quantum-limited sensing technology and pixelated silicon sensors to search for new invisible particles. The design features a nanometer-scale, optically levitated sensor embedded with unstable radioisotopes, and surrounded by pixelated silicon detectors. By measuring the recoil of the optomechanical sensor at the...
