Sagnac-type neutron displacement-noise-free interferometeric gravitational-wave detector
Yuki Kawasaki, Shoki Iwaguchi, Tomohiro Ishikawa +13
The detection of low-frequency gravitational waves on Earth requires the reduction of displacement noise, which dominates the low-frequency band. One method to cancel test mass dis…

Optimization of quantum noise in space gravitational-wave antenna DECIGO with optical-spring quantum locking considering mixture of vacuum fluctuations in homodyne detection
Kenji Tsuji, Tomohiro Ishikawa, Kentaro Komori +10
Quantum locking using optical spring and homodyne detection has been devised to reduce quantum noise that limits the sensitivity of DECIGO, a space-based gravitational wave antenna…
