The ultracold gas system offers a platform that is clean and controlled. We constructed a mixture system involving two atom species: Cs and Li, of large mass imbalance and different statistics, aiming at simulating the interaction\u0026nbsp;between electrons and impurities in materials, which are believed to give rise to different electric conductivity and magnetism behaviors described by the Kondo Problem and RKKY theory. The system combines the optics and atom source of Cs system with an existing Li platform, where the Cs source is a portable module featuring a custom 2D-MOT (Magneto-Optical Trap).\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EIn the talk, I will also present our experiments on dynamics of a Li molecular BEC in a shaken optical lattice, in which we observed an unexpected continuous bifurcation in momentum space caused by the modified dispersion. We demonstrate how the bifurcation can be understood through GPE (Gross Pitaevskii Equation) and simulations, and its implication on a soliton enabled through interactions.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EDynamics in an Ultracold Quantum Gas System for Mixtures\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Dynamics in an Ultracold Quantum Gas System for Mixtures "}],"uid":"27707","created_gmt":"2024-07-01 19:47:34","changed_gmt":"2024-07-01 19:48:00","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2024-07-02T13:30:00-04:00","event_time_end":"2024-07-08T14:30:00-04:00","event_time_end_last":"2024-07-08T14:30:00-04:00","gmt_time_start":"2024-07-02 17:30:00","gmt_time_end":"2024-07-08 18:30:00","gmt_time_end_last":"2024-07-08 18:30:00","rrule":null,"timezone":"America\/New_York"},"location":"Howey Physics Building, N201\/202","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
