Optomechanical probe of an axial-vector mediated interaction in the quantum regime.

Abstract

We present an atomic, molecular, and optical physics based method to search for axial-vector mediated dipole-dipole interaction between electrons. In our optomechanical scheme, applying a static magnetic field and a pump beam and a probe beam to a hybrid mechanical system composed of a nitrogen-vacancy center and a cantilever resonator, we could obtain a probe absorption spectrum. Based on the study of the relationship between this spectrum and the exotic dipole-dipole interaction, we put forward our detection principle and then provide a prospective constraint most stringent at a rough interaction range from 4 × 10-8 to 2 × 10-7m. Our results indicate that this scheme could be put into consideration in relevant experimental searches.
