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-frequenc…
Mode hitching in traveling-wave optical parametric amplification
Joseph Kelly, Eleanor Fradgley, Lida Zhang +1
Optical parametric amplifiers (OPAs) in traveling wave configuration can generate localized spatial quantum correlations between a signal and an idler beam, a useful resource for q…
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…
DarkGEO: A Large-Scale Laser-Interferometric Axion Detector
Joscha Heinze, Alex Gill, Artemiy Dmitriev +8
Axions and axion-like particles (ALPs) are leading candidates for dark matter. They are well motivated in many extensions of the Standard Model and supported by astronomical observ…
