Reduction of quantum noise using the quantum locking with an optical spring for gravitational wave detectors
Rika Yamada, Yutaro Enomoto, Izumi Watanabe +11
In our previous research, simulation showed that a quantum locking scheme with homodyne detection in sub-cavities is effective in surpassing the quantum noise limit for Deci-hertz…
Quantum noise in a Fabry-Perot interferometer including the influence of diffraction loss of light
Shoki. Iwaguchi, Tomohiro. Ishikawa, Masaki. Ando +10
The DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is designed to detect gravitational waves at frequencies between 0.1 and 10 Hz. In this frequency band, one of…
Improvement of the target sensitivity in DECIGO by optimizing its parameters for quantum noise including the effect of diffraction loss
Tomohiro Ishikawa, Shoki Iwaguchi, Yuta Michimura +10
DECIGO is the future Japanese gravitational wave detector in outer space. We previously set the default design parameters to provide a good target sensitivity to detect the primord…
Improved sensitivity of interferometric gravitational wave detectors to ultralight vector dark matter from the finite light-traveling time
Soichiro Morisaki, Tomohiro Fujita, Yuta Michimura +2
Recently several studies have pointed out that gravitational-wave detectors are sensitive to ultralight vector dark matter and can improve the current best constraints given by the…
Cryogenic suspension design for a kilometer-scale gravitational-wave detector
Takafumi Ushiba, Tomotada Akutsu, Yoichi Aso +43
We report the mirror suspension design for Large-scale Cryogenic Gravitational wave Telescope, KAGRA, during bKAGRA Phase 1. Mirror thermal noise is one of the fundamental noises f…
Overview of KAGRA : KAGRA science
KAGRA Collaboration, T. Akutsu, M. Ando +240
KAGRA is a newly build gravitational-wave observatory, a laser interferometer with 3 km arm length, located in Kamioka, Gifu, Japan. In this paper in the series of KAGRA-featured a…
