Smith, Kevin Schulz and Poul S. Jessen<br \/><\/strong>\u00a0<\/p>\n<p class=\"center\" style=\"text-align: center\">We demonstrate a weak continuous measurement of the pseudo-spin associated with the clock transition in a sample of Cs atoms. Our scheme uses an optical probe tuned near the D1 transition to measure the sample birefringence, which depends on the z-component of the collective pseudospin. At certain probe frequencies the differential light shift of the clock states vanishes and the measurement is non-perturbing. In dense samples the measurement can be used to squeeze the collective clock pseudo-spin, and has potential to improve the performance of atomic clocks and interferometers.<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\/21_clock.pdf\">Full Text<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Continuous Non-demolition Measurement of the Cs Clock Transition Pseudo-spin<\/p>\n","protected":false},"author":245,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[32,1],"tags":[],"class_list":["post-346","post","type-post","status-publish","format-standard","hentry","category-32","category-abstracts"],"_links":{"self":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/346","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\/245"}],"replies":[{"embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/comments?post=346"}],"version-history":[{"count":1,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/346\/revisions"}],"predecessor-version":[{"id":347,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/346\/revisions\/347"}],"wp:attachment":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/media?parent=346"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/categories?post=346"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/tags?post=346"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
