Extending Ground-Based Gravitational-Wave Sensitivity to 5 Hz
Amit Singh Ubhi, Lari Koponen, Jiri Smetana +11
Extending the sensitivity of terrestrial gravitational-wave detectors below 20 Hz is a long-standing challenge, limited by ground motion and inertial sensing noise. In this letter,…
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…
Sensitivity and control of a 6-axis fused-silica seismometer
Jiri Smetana, Amit Singh Ubhi, Emilia Chick +12
We present a pair of seismometers capable of measurement in all six axes of rigid motion. The vacuum-compatible devices implement compact interferometric displacement sensors to su…
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…
Design and sensitivity of a 6-axis seismometer for gravitational wave observatories
Leonid Prokhorov, Sam Cooper, Amit Singh Ubhi +13
We present the design, control system, and noise analysis of a 6-axis seismometer comprising a mass suspended by a single fused silica fibre. We utilise custom-made, compact Michel…
