@article{Qvarfort2021ConstrainingMG, title={Constraining modified gravity with quantum optomechanics}, author={Sofia Qvarfort and Dennis R{\"a}tzel and Stephen Stopyra}, journal={New Journal of Physics}, year={2021}, volume={24} }

We derive the best possible bounds that can be placed on Yukawa- and chameleon-like modifications to the Newtonian gravitational potential with a cavity optomechanical quantum sensor. By modelling the effects on an oscillating source-sphere on the optomechanical system from first-principles, we derive the fundamental sensitivity with which these modifications can be detected in the absence of environmental noise. In particular, we take into account the large size of the optomechanical probe…
