Abstract
The nature of dark energy is the most compelling of all outstanding problems in physical science. Although various theories for dark energy have been proposed, experimental verification or exclusion of these theories has been faced with tremendous challenges not only at cosmic scales, but also at laboratory scales. In this work, we use a levitated force sensor to detect the fifth force predicted by the chameleon theory, one of the most compelling theories for dark energy. With no signatures of the fifth force detected, we decisively rule out, for the first time, the basic chameleon model as a candidate for dark energy.
