Resonant speed meter for gravitational wave detection
Atsushi Nishizawa, Seiji Kawamura, Masa-aki Sakagami
Gravitational-wave detectors have been well developed and operated with high sensitivity. However, they still suffer from mirror displacement noise. In this paper, we propose a res…
Experimental investigation of a control scheme for a zero-detuning resonant sideband extraction interferometer for next-generation gravitational-wave detectors
Fumiko Kawazoe, Mitsuhiro Fukushima, Seiji Kawamura +8
Some next-generation gravitational-wave detectors, such as the American Advanced LIGO project and the Japanese LCGT project, plan to use power recycled resonant sideband extraction…
Search for a stochastic background of 100-MHz gravitational waves with laser interferometers
Tomotada Akutsu, Seiji Kawamura, Atsushi Nishizawa +11
This letter reports the results of a search for a stochastic background of gravitational waves (GW) at 100 MHz by laser interferometry. We have developed a GW detector, which is a…
Optimal Location of Two Laser-interferometric Detectors for Gravitational Wave Backgrounds at 100 MHz
Atsushi Nishizawa, Seiji Kawamura, Tomotada Akutsu +8
Recently, observational searches for gravitational wave background (GWB) have been developed and given constraints on the energy density of GWB in a broad range of frequencies. The…
Laser-interferometric Detectors for Gravitational Wave Background at 100 MHz : Detector Design and Sensitivity
Atsushi Nishizawa, Seiji Kawamura, Tomotada Akutsu +8
Recently, observational searches for gravitational wave background (GWB) have developed and given direct and indirect constraints on the energy density of GWB in a broad range of f…
Quantum Noise in Differential-type Gravitational-wave Interferometer and Signal Recycling
Atsushi Nishizawa, Seiji Kawamura, Masa-aki Sakagami
There exists the standard quantum limit (SQL), derived from Heisenberg's uncertainty relation, in the sensitivity of laser interferometer gravitational-wave detectors. However, in…
