Optical trapping of the transversal motion for an optically levitated mirror
Takuya Kawasaki, Naoki Kita, Koji Nagano +4
Optomechanical systems are suitable for elucidating quantum phenomena at the macroscopic scale in the sense of the mass scale. The systems should be well-isolated from the environm…
Construction of KAGRA: an Underground Gravitational Wave Observatory
T. Akutsu, M. Ando, S. Araki +222
Major construction and initial-phase operation of a second-generation gravitational-wave detector KAGRA has been completed. The entire 3-km detector is installed underground in a m…
Optical Levitation of a Mirror for Reaching the Standard Quantum Limit
Yuta Michimura, Yuya Kuwahara, Takafumi Ushiba +2
We propose a new method to optically levitate a macroscopic mirror with two vertical Fabry-P{é}rot cavities linearly aligned. This configuration gives the simplest possible optical…
Ground Based Low-Frequency Gravitational-wave Detector With Multiple Outputs
Ayaka Shoda, Yuya Kuwahara, Masaki Ando +4
We have developed a new gravitaional-wave (GW) detector, TOrsion-Bar Antenna (TOBA), with multiple-output configuration. TOBA is a detector with bar-shaped test masses that rotate…
Search for a stochastic gravitational wave background at 1-5 Hz with Torsion-bar Antenna
Yuya Kuwahara, Ayaka Shoda, Kazunari Eda +1
We set the first upper limit on the stochastic gravitational wave (GW) background in the frequency range of using a Torsion-bar Antenna (TOBA). A TOBA is a GW de…
All-sky coherent search for continuous gravitational waves in 6-7 Hz band with a torsion-bar antenna
Kazunari Eda, Ayaka Shoda, Yuya Kuwahara +2
A torsion-bar antenna (TOBA) is a low-frequency terrestrial gravitational wave (GW) antenna which consists of two orthogonal bar-shaped test masses. We upgraded the prototype TOBA…
