We propose an optomechanical nano-gravimeter based on exceptional points. Thesystem is a coupled cavity optomechanical system, in which the gain and lossare applied by driving the cavities with a blue detuned and red detunedelectromagnetic field, respectively. When the gain and loss reach a balance,the system will show the degeneracy of exceptional points, and any perturbationwill cause an eigenfrequencies split, which is proportional to the square rootof the perturbation strength. Compared with the traditional optomechanicalsensors, the sensitivity is greatly enhanced. This work paves the way for thedesign of optomechanical ultrasensitive force sensors that can be applied todetect non-Newtonian effects, high-order weak interactions, and so on.

Enhanced sensing of non-Newtonian effects at ultrashort range with exceptional points in optomechanical systems
