Torsional-X Seismometer for Lunar Decihertz Gravitational-Wave Detection
Yulin Xia, Denis Martynov, Huan Yang +1
The lunar gravitational-wave antenna concept uses the Moon as a resonant detector instrumented with precision seismometers, targeting the decihertz band between ground- and space-b…
Notes on Images and Communication
Denis Martynov
This is an active module taught to Bachelor's and Master's students at the University of Birmingham since 2021, covering selected topics in applied optics with an emphasis on imagi…
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-frequen…
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…
Merging L-shaped resonator with Michelson configuration for kilohertz gravitational-wave detection
Xinyao Guo, Teng Zhang, Denis Martynov +1
Detection of gravitational waves in kilohertz frequency range is crucial for understanding the physical processes of binary neutron star mergers. In Ref. [Phys. Rev. X {\bf 13}, 02…
