Can the phase of radiation pressure fluctuations be flipped in a single path for laser interferometric gravitational wave detectors?
Tomohiro Ishikawa, Shoki Iwaguchi, Bin Wu +7
Radiation pressure (RP) noise, one component of quantum noise, can limit the sensitivity of laser interferometric gravitational wave (GW) detectors at lower frequencies. We conceiv…
Displacement-noise-free neutron interferometer for gravitational wave detection using a single Mach-Zehnder configuration
Shoki Iwaguchi, Atsushi Nishizawa, Yanbei Chen +10
The improvement of sensitivity to gravitational waves (GWs) at lower frequencies is still challenging on account of displacement noise. One of the solutions is the neutron displace…
Optimization of Design Parameters for Gravitational Wave Detector DECIGO Including Fundamental Noises
Yuki Kawasaki, Ryuma Shimizu, Tomohiro Ishikawa +6
The DECi hertz Interferometer Gravitational-Wave Observatory (DECIGO) is a space gravitational wave (GW) detector. DECIGO was originally designed to be sensitive enough to observe…
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…
