First result for testing semiclassical gravity effect with a torsion balance
Tianliang Yan, Yubao Liu, Leonid Prokhorov +5
The Schrödinger-Newton equation, a theoretical framework connecting quantum mechanics with classical gravity, predicts that gravity may induce measurable deviations in low-frequen…

Approaches of frequency-dependent squeezing for the low frequency detector of Einstein Telescope
Xingrui Peng, Denis Martynov, Zonghong Zhu +1
The quantum noise in gravitational-wave detectors can be suppressed in a broadband by frequency-dependent squeezing. It usually requires one large scale filter cavity and even two,…

A High-Finesse Suspended Interferometric Sensor for Macroscopic Quantum Mechanics with Femtometre Sensitivity
Jiri Smetana, Tianliang Yan, Vincent Boyer +1
We present an interferometric sensor for investigating macroscopic quantum mechanics on a table-top scale. The sensor consists of pair of suspended optical cavities with a finesse…
