Research Abstract

We developed a precise torsion pendulum using magnetic levitation by super-conductor and a laser interferometer, and tested the short-range inverse-square-law of gravity. In addition, we set a new upper limit on the energy density of gravitational-wave background at around 0.1Hz band.
