Introduction of new analysis for atomic gravitational microlaboratories

Abstract

This document briefly reviews recent short-range gravity experiments that were performed at below laboratory scales to test the Newtonian inverse square law of gravity. To compare sensitivities of these measurements, estimates using the conventional Yukawa parametrization are introduced. Since these experiments were triggered by the prediction of the large extra-dimension model, experiments performed at different length scales are compared with this prediction. In this paper, a direct comparison between laboratory-scale experiments and the LHC results is presented for the first time. A laboratory experiment is shown to determine the best limit at $M_D > 4.6 \;\rm{TeV}$ and $\lambda<23 \;\mu \rm{m}$. In addition, new analysis results are described for atomic systems used as gravitational microlaboratories.
