Photothermal effect in macroscopic optomechanical systems with an intracavity nonlinear optical crystal
Sotatsu Otabe, Kentaro Komori, Ken-ichi Harada +3
Intracavity squeezing is a promising technique that may improve the sensitivity of gravitational wave detectors and cool optomechanical oscillators to the ground state. However, th…
Improving force sensitivity by amplitude measurement of light reflected from a detuned optomechanical cavity
Kentaro Komori, Takuya Kawasaki, Sotatsu Otabe +3
The measurement of weak continuous forces exerted on a mechanical oscillator is a fundamental problem in various physical experiments. It is fundamentally impeded by quantum back-a…
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…
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…
