Fundamental quantum limits for detecting ultrahigh frequency gravitational waves
Xinyao Guo, Haixing Miao, Zhi-Wei Wang +2
The ultrahigh-frequency (above 10 kHz) gravitational waves (GW) window provides a unique opportunity to detect primordial GWs, free from astrophysical foregrounds that dominate low…

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…
