A Polarization-Decomposed Method for Simulating Inhomogeneous Birefringence in Laser-Interferometric Gravitational-Wave Detectors
Haoyu Wang, Yuta Michimura, Keiko Kokeyama +9
Birefringence in test mass substrates is an emerging limitation for current and future laser-interferometric gravitational-wave detectors, particularly as detectors move toward hig…
Initial acquisition requirements for optical cavities in the space gravitational wave antennae DECIGO and B-DECIGO
Yuta Michimura, Koji Nagano, Kentaro Komori +8
DECIGO (DECi-hertz Interferometer Gravitational Wave Observatory) is a space-based gravitational wave antenna concept targeting the 0.1-10 Hz band. It consists of three spacecraft…
Adjusting optical cavity birefringence with wavelength tunable laser for axion searches
Hinata Takidera, Hiroki Fujimoto, Yuka Oshima +6
Axions have attracted attention as promising candidates for dark matter (DM). Although axions have been intensively searched for, they have not been observed yet. Recently, novel e…
SILVIA: Ultra-precision formation flying demonstration for space-based interferometry
Takahiro Ito, Kiwamu Izumi, Isao Kawano +26
We propose SILVIA (Space Interferometer Laboratory Voyaging towards Innovative Applications), a mission concept designed to demonstrate ultra-precision formation flying between thr…
Cross-Correlated Force Measurement for Thermal Noise Reduction in Torsion Pendulum
Yusuke Okuma, Kiwamu Izumi, Kentaro Komori +1
The torsion pendulum is a prevailing instrument for measuring small forces acting on a solid body or those between solid bodies. While it offers powerful advantages, the measuremen…
TOrsion-Bar Antenna: A Ground-Based Detector for Low-Frequency Gravity Gradient Measurement
Satoru Takano, Tomofumi Shimoda, Yuka Oshima +12
The Torsion-Bar Antenna (TOBA) is a torsion pendulum-based gravitational detector developed to observe gravitational waves in frequencies between 1 mHz and 10 Hz. The low resonant…
