Lund / Getty Images]</p> </div><p>“The microwave trap has the ability to trap any spin state ... In this first demonstration, laser-cooled cesium atoms, having a temperature below 5 μK, were trapped in the field of a resonant microwave cavity. The gradient of the microwave field intensity produced a spatial variation of the atom-microwave interaction energy that created a trap as deep as 100 μK. A small cloud of atoms released into such a trap oscillated about the trap center until collisions with hot, untrapped background gas atoms kicked the atoms out.”</p>…</div> <div class="alert alert-warning clearfix"> <div class="row"> <div class="col-1"> <span class="fas fa-lock fa-3x"></span> </div> <div class="col"> <h4><a href="/account/login?returnUrl=%2Fhome%2Farticles%2Fvolume_35%2Fdecember_2024%2Fdepartments%2F30_20_and_10_years_ago_in_opn%2F">Log in</a> or <a href="https://account.optica.org/eweb/dynamicpage.aspx?webcode=member&mbr_src_code=OPNWEB" target="_blank">become a member</a> to view the full text of this article.</h4> <br/> <p> This article may be available for purchase via the <a href="https://opg.optica.org/search.cfm?q=&meta=1&j=opn,optics-news&i=12&cj=1&cc=0&sy=2024&ey=2024" target="_blank">search at Optica Publishing Group</a>. <br/> Optica Members get the full text of <em>Optics & Photonics News</em>, plus a variety of other <a href="https://www.optica.org/en-us/membership_education/benefits_and_services/?utm_source=OPN&utm_medium=Magazine&utm_content=ArticleBenefitsLink&utm_campaign=Article%20Access%20Benefits%20Link" target="_blank">member benefits</a>. </p> </div> </div> </div> </div> <h3> <a id="comments">Add a Comment</a> </h3> <div id="disqus_thread"></div> <script> /** * RECOMMENDED CONFIGURATION VARIABLES: EDIT AND UNCOMMENT THE SECTION BELOW TO INSERT DYNAMIC VALUES FROM YOUR PLATFORM OR CMS. * LEARN WHY DEFINING THESE VARIABLES IS IMPORTANT: https://disqus.com/admin/universalcode/#configuration-variables */ var disqus_config = function () { this.page.url = "https://www.optica-opn.org" + "/home/articles/volume_35/december_2024/departments/30_20_and_10_years_ago_in_opn/"; // Replace PAGE_URL with your page's canonical URL variable this.page.identifier = "30, 20 and 10 Years Ago in OPN"; // Replace PAGE_IDENTIFIER with your page's unique identifier variable }; (function() { // DON'T EDIT BELOW THIS LINE var d = document, s = d.createElement('script'); s.src = 'https://opticsphotonicsnews.disqus.com/embed.js'; s.setAttribute('data-timestamp', +new Date()); (d.head || d.body).appendChild(s); })(); </script> <noscript>Please enable JavaScript to view the <a href="https://disqus.com/?ref_noscript">comments powered by Disqus.</a></noscript> <script type="application/ld+json"> { "@context": "http://schema.org", "@type": "NewsArticle", "mainEntityOfPage": { "@type": "WebPage", "@id": "https://www.osa-opn.org" }, "headline": "30, 20 and 10 Years Ago in OPN", "datePublished": "2024-12-01T11:19:04-05:00", "dateModified": "0001-01-01T0:00:00-05:00", "author": { "@type": "Person", "name": "Rachel Sender" }, "publisher": { "@type": "Organization", "name": "Optics & Photonics News", "logo": { "@type": "ImageObject", "url": "https://www.osa-opn.org/opn/media/images/header/OPNbanner_left.jpg" } }, "description": "@Html.UrlEncoder.Encode(Model.ItemDescription)", "isAccessibleForFree": "False", "hasPart": { "@type": "WebPageElement", "isAccessibleForFree": "False", "cssSelector" : ".restrictedaccess" } } </script> <meta name="twitter:card" content="summary_large_image"> <meta name="twitter:site" content="@OPNmagazine"> <meta name="twitter:title" content="30, 20 and 10 Years Ago in OPN"> <meta name="twitter:description" content="<p>Microwave trap; hollow-core Bragg fibers; spontaneous spatial organization of a cold atomic cloud.</p>
