Precision measurements of macroscopic objects have been a challenge, but now a research team has demonstrated a significant sensitivity improvement with a levitated object some 6 orders of magnitude larger than in previous experiments [<a href=\"https:\/\/physics.aps.org\/articles\/v19\/84#c1\">1<\/a>]. The team hopes the method will find use in experimental searches in the next few years.<\/p>\n<p>Searching for particles not accounted for by the standard model of particle physics requires experiments with unprecedented sensitivity. One method is to use laser light to levitate a small object in a vacuum, isolating it from surrounding noise. Researchers can monitor its motion and potentially detect minuscule recoils caused by rare collisions with exotic particles, such as those of dark matter.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers boosted the sensitivity for measurements of the motion of a levitated nanoparticle, with potential uses in dark matter searches.
