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…

Searches for ultralight vector and axion dark matter with KAGRA
Yuta Michimura, Takumi Fujimori, Hiroki Fujimoto +10
We have proposed using laser interferometric gravitational wave detectors to search for ultralight vector and axion dark matter. Vector dark matter can be probed through oscillatin…

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…
