Whitaker<\/p>\n<p>We have developed a system to create Bose-Einstein condensates (BECs) in a time varying optical dipole trap produced by a single focused CO<sub>2<\/sub> laser.   Our system can cool up to a million atoms to quantum degeneracy in any hyperfine states.  We have also found that our trap provides a temperature stability and precision that is better than any conventional&#8221; BEC system that cools atoms in a magnetic trap.   Our unprecedented temperature control will be used probe BECs very near the critical temperature and to gain insight into the nature of quantum phase transitions, which have a number of universal properties and occur in other systems such as superfluid helium and superconductors.&#8221;<\/p>\n","protected":false},"author":1,"featured_media":0,"template":"","class_list":["post-3915","physics_colloquium","type-physics_colloquium","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium\/3915","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium"}],"about":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/types\/physics_colloquium"}],"author":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/users\/1"}],"wp:attachment":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/media?parent=3915"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
