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…
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…
New Limit on Lorentz Violation Using a Double-Pass Optical Ring Cavity
Yuta Michimura, Nobuyuki Matsumoto, Noriaki Ohmae +4
A search for Lorentz violation in electrodynamics was performed by measuring the resonant frequency difference between two counterpropagating directions of an optical ring cavity.…
