Quantum Noise Reduction in the Space-based Gravitational Wave Antenna DECIGO Using Optical Springs and Homodyne Detection scheme
Kenji Tsuji, Tomohiro Ishikawa, Kentaro Komori +6
The DECi-hertz Interferometer Gravitational-wave Observatory (DECIGO) is a planned space-based, next-generation gravitational wave detector aimed at observing primordial gravitatio…
Adjusting optical cavity birefringence with wavelength tunable laser for axion searches
Hinata Takidera, Hiroki Fujimoto, Yuka Oshima +6
Axions have attracted attention as promising candidates for dark matter (DM). Although axions have been intensively searched for, they have not been observed yet. Recently, novel e…
Quantum Noise from Vacuum Field Injection in Optical Cavities with Diffraction-related Loss
Kurumi Umemura, Tomohiro Ishikawa, Kenji Tsuji +6
The space-based gravitational wave detector DECIGO is designed to observe primordial gravitational waves with 1,000 km Fabry-Perot cavities. Its sensitivity is limited by quantum n…
Observation of an Optical Spring in a Robustly Controlled Signal-Recycled Michelson Interferometer
Kaido Suzuki, Ken-ichi Harada, Ryo Iden +4
We present, to the best of our knowledge, the first demonstration of an optical spring in a signal-recycled Michelson interferometer without arm cavities. The setup utilizes multip…
SILVIA: Ultra-precision formation flying demonstration for space-based interferometry
Takahiro Ito, Kiwamu Izumi, Isao Kawano +26
We propose SILVIA (Space Interferometer Laboratory Voyaging towards Innovative Applications), a mission concept designed to demonstrate ultra-precision formation flying between thr…
Initial acquisition requirements for optical cavities in the space gravitational wave antennae DECIGO and B-DECIGO
Yuta Michimura, Koji Nagano, Kentaro Komori +8
DECIGO (DECi-hertz Interferometer Gravitational Wave Observatory) is a space-based gravitational wave antenna concept targeting the 0.1-10 Hz band. It consists of three spacecraft…
Searches for ultralight vector and axion dark matter with KAGRA
Yuta Michimura, Takumi Fujimori, Hiroki Fujimoto +10
We have proposed using laser interferometric gravitational wave detectors to search for ultralight vector and axion dark matter. Vector dark matter can be probed through oscillatin…
