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…
Kerr-Enhanced Optical Spring
Sotatsu Otabe, Wataru Usukura, Kaido Suzuki +4
We propose and experimentally demonstrate the generation of enhanced optical springs using the optical Kerr effect. A nonlinear optical crystal is inserted into a Fabry-Perot cavit…
Inverted Oscillators for Testing Gravity-induced Quantum Entanglement
Tomohiro Fujita, Youka Kaku, Akira Matsumura +1
In the quest for quantum gravity, we have lacked experimental verification, hampered by the weakness of gravity and decoherence. Recently, various experiments have been proposed to…
Effects of mirror birefringence and its fluctuations to laser interferometric gravitational wave detectors
Yuta Michimura, Haoyu Wang, Francisco Salces-Carcoba +4
Crystalline materials are promising candidates as substrates or high-reflective coatings of mirrors to reduce thermal noises in future laser interferometric gravitational wave dete…
