Constraining the axion-nucleon coupling and non-Newtonian gravity with a levitated optomechanical device

Abstract

In the paper, we propose a scheme to constrain the axion-to-nucleon interaction and non-Newtonian gravity. Here, we consider a levitated optomechanical system consisting of a silica nanosphere and an optical cavity. The total force gradient exerted on this nanosphere modifies its resonance frequency. Based on this, we have developed a quantum optical method to detect and constrain the two exotic forces. Also, we have established prospective constraints on axion-neucleon coupling constants and the Yukawa interaction constant. In addition, these constraints significantly improve the existing bounds.
