From this follows a demand to establish a pool of specialized, increasingly precise spectroscopic interrogation techniques. By combining saturated cavity ring-down spectroscopy with the buffer-gas-cooling technique, we have demonstrated a general approach to Lamb-dip ro-vibrational measurements on cold molecules. The developed scheme represents the launch pad to high-accuracy molecular tests of fundamental Physics at the electron volt energy scale. Examples include: searching for fifth-force interactions, assessing the space-time stability of the proton-to-electron mass ratio, and probing parity violation in chiral molecules.<\/p>\n<p>The research is published in <a href=\"https:\/\/www.osapublishing.org\/optica\/abstract.cfm?uri=optica-6-4-436&amp;origin=search\">Optica<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nowadays, buffer gas cooling represents an invaluable option to produce cold stable molecules, both in view of secondary cooling\/trapping strategies towards the achievement of quantum degeneracy<span class=\"excerpt-hellip\"> [\u2026]<\/span><\/p>\n","protected":false},"author":547,"featured_media":14754,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[33],"tags":[],"class_list":["post-14739","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-researchfocus"],"_links":{"self":[{"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/posts\/14739","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/users\/547"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=14739"}],"version-history":[{"count":15,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/posts\/14739\/revisions"}],"predecessor-version":[{"id":14758,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/posts\/14739\/revisions\/14758"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/media\/14754"}],"wp:attachment":[{"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=14739"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=14739"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=14739"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
