Vector field dark matter search with Sagnac interferometer
Yuki Inoue, Quynh Lan Nguyen, Ippei Obata
We present the first calculation showing that a material-asymmetric Sagnac speed meter can improve quantum-noise-limited sensitivity to vector dark matter by nearly two order…
Estimation of systematic error from bulk deformation of end test mass induced by photon calibrator for LIGO post-O5 gravitational wave projects
Daiki Tanabe, Aloysius Niko, Kun-Yao Chang +4
We studied the bulk deformation of the end test masses (ETMs) of gravitational wave (GW) detectors caused by calibration devices named Photon Calibrator (Pcal). This bulk deformati…
Noise reduction in suspension control with photon-pressure actuator for CHRONOS gravitational wave detector
Daiki Tanabe, Yuki Inoue, Mario Juvenal S. Onglao
Improving sub-Hz sensitivity of gravitational wave (GW) detectors is important to detect heavier binary black hole mergers and study phenomena in stronger gravity fields. Torsion-b…
CHRONOS: Cryogenic sub-Hz cROss torsion bar detector with quantum NOn-demolition Speed meter
Yuki Inoue, Hsiang-Chieh Hsu, Hsiang-Yu Huang +7
We propose a next-generation ground-based gravitational-wave detector, Cryogenic sub-Hz cROss torsion-bar detector with quantum NOn-demolition Speed meter (CHRONOS), optimized for…
