In the optical lattice we precool the atoms to ~1 \u03bcK. We then reduce the trapping potential in a few hundred \u03bcs, causing the atomic center-of-mass distribution to expand and the temperature to decrease by an amount which agrees with a simple 3D band theory. These are the lowest 3D kinetic temperatures ever measured.<br \/>\u00a0<\/p>\n<p class=\"center\" style=\"text-align: center\"><a href=\"https:\/\/wp.optics.arizona.edu\/pjessen\/publications\/\">Back<\/a> | <a href=\"http:\/\/wp.optics.arizona.edu\/pjessen\/wp-content\/uploads\/sites\/116\/2022\/12\/01_adiabat.pdf\">Full Text<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Adiabatic Cooling of Cesium to 700 nK in an Optical Lattice<\/p>\n","protected":false},"author":91,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[17,1],"tags":[],"class_list":["post-246","post","type-post","status-publish","format-standard","hentry","category-17","category-abstracts"],"_links":{"self":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/246","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/users\/91"}],"replies":[{"embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/comments?post=246"}],"version-history":[{"count":7,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/246\/revisions"}],"predecessor-version":[{"id":277,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/246\/revisions\/277"}],"wp:attachment":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/media?parent=246"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/categories?post=246"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/tags?post=246"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
