Axion Search with Ring Cavity Experiment
Ippei Obata, Tomohiro Fujita, Yuta Michimura
We suggest a novel experimental method to search for axion dark matter with an optical ring cavity. Our cavity measures the difference of the resonant frequencies between two circu…
KAGRA: 2.5 Generation Interferometric Gravitational Wave Detector
T. Akutsu, M. Ando, K. Arai +188
The recent detections of gravitational waves (GWs) reported by LIGO/Virgo collaborations have made significant impact on physics and astronomy. A global network of GW detectors wil…
Demonstration of displacement sensing of a mg-scale pendulum for mm- and mg- scale gravity measurements
Nobuyuki Matsumoto, Masakazu Sugawara, Seiya Suzuki +6
Gravity generated by large masses has been observed using a variety of probes from atomic interferometers to torsional balances. However, gravitational coupling between small masse…
Polarization test of gravitational waves from compact binary coalescences
Hiroki Takeda, Atsushi Nishizawa, Yuta Michimura +4
Gravitational waves have only two polarization modes in General Relativity. However, there are six possible modes of polarization in metric theory of gravity in general. The tests…
Optical Ring Cavity Search for Axion Dark Matter
Ippei Obata, Tomohiro Fujita, Yuta Michimura
We propose a novel experiment to search for axion dark matter which differentiates the phase velocities of the left and right-handed polarized photons. Our optical cavity measures…
Particle swarm optimization of the sensitivity of a cryogenic gravitational wave detector
Yuta Michimura, Kentaro Komori, Atsushi Nishizawa +6
Cryogenic cooling of the test masses of interferometric gravitational wave detectors is a promising way to reduce thermal noise. However, cryogenic cooling limits the incident powe…
