5-mg suspended mirror driven by measurement-induced back-action
Nobuyuki Matsumoto, Kentaro Komori, Yuta Michimura +3
Quantum mechanics predicts superposition of position states even for macroscopic objects. Recently, the use of a quasi-freely suspended mirror combined with laser was proposed to p…
Search for a Stochastic Gravitational-wave Background using a pair of Torsion-bar Antennas
Ayaka Shoda, Masaki Ando, Koji Ishidoshiro +4
We have set a new upper limit on the stochastic gravitational wave background (SGWB) using two prototype Torsion-bar Antennas (TOBAs). TOBA is a low-frequency gravitational-wave de…
Optical-Cavity Limits on Higher-Order Lorentz Violation
Yuta Michimura, Matthew Mewes, Nobuyuki Matsumoto +2
An optical ring cavity is used to place the first laboratory constraints on parity-odd nonrenormalizable Lorentz violation. Variations in resonant frequencies are limited to parts…
Testing Lorentz Invariance with a Double-Pass Optical Ring Cavity
Yuta Michimura, Nobuyuki Matsumoto, Noriaki Ohmae +4
We have developed an apparatus to test Lorentz invariance in the photon sector by measuring the resonant frequency difference between two counterpropagating directions of an asymme…
Interferometer design of the KAGRA gravitational wave detector
Yoichi Aso, Yuta Michimura, Kentaro Somiya +5
KAGRA is a cryogenic interferometric gravitational wave detector being constructed at the underground site of Kamioka mine in Gifu prefecture, Japan. We performed an optimization o…
Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO, Advanced Virgo and KAGRA
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1319
We present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years,…
