We theoretically investigate the model of a quadratically coupled optomechanical system with a Newtonian gravitational potential in the weak-driving regime, where the optical cavity is driven by an ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where a particle does not have a single definite value of position or momentum ...

Physicists at Kyushu University in Japan have outlined a technique that could bring one of the most elusive goals in modern physics closer to the laboratory bench: detecting signs that gravity obeys ...

Laser light is injected into an optical cavity to continuously measure the position of a movable mirror. The output light is read out by homodyne detection, and the measurement data are analyzed using ...

A network of optical cavities could be used to detect gravitational waves (GWs) in an unexplored range of frequencies, according to researchers in the UK. Using technology already within reach, the ...
