Physicist Andrew Truscott and his colleagues at the Australian National University, in the city of Canberra, used magnetic fields to trap 10,000 helium atoms cooled to a state of matter known as a Bose-Einstein condensate, in which all atoms behave in unison, like a single larger atom. Then, they used an electric field to increase the number of collisions between the atoms in the condensate, pushing them out of the trap in pairs (<em>Physical Review Letters<\/em>, September 24, 2014). So if an odd number of helium atoms was initially present in the trap, a single atom would be left in the end, at a temperature of just 890 trillionths of a degree Celsius (\u00b0C) above absolute zero (-273\u00b0C). Under the laws of quantum mechanics, an atom cooled to such low temperatures behaves more like a wave than a particle, which means that the atoms isolated by the new technique will be perfect for testing quantum phenomena like entanglement, which has already been tested using pairs of light particles.<\/p>\n","protected":false},"excerpt":{"rendered":"New technique uses magnetic fields to isolate atoms","protected":false},"author":475,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[168],"tags":[235],"coauthors":[785],"class_list":["post-162301","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-physics"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/162301","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=162301"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/162301\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=162301"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=162301"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=162301"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=162301"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
