In this talk, I will discuss our recent investigation on \u201cselective radiance,\u201d a phenomenon in which an atomic excitation couples to a specific photonic channel with collective enhancement (called \u2018superradiance\u2019) but to all other channels with suppression (\u2018subradiance\u2019). Following our recent experimental realization of cold atom trapping on a nanophotonic microring resonator, we study how a dense atomic ensemble collectively couples to a whispering-gallery-mode in the resonator and to other free space modes. I will discuss the decay dynamics of an atomic ensemble following long and short excitation pulses, with the former driving the system into a steady state and the latter into a so-called timed-Dicke state. I will discuss the potential of our platform to realize selective radiance in an atom array and explore collective quantum optics with trapped atoms coupled to nanophotonic circuits. \r\n\r\nBio. Dr. Hung received his PhD in Physics at the University of Chicago in 2011, where he developed an in-situ microscopy technique on two-dimensional atomic quantum gases to study quantum phase transitions. Before joining Purdue in 2015 as a faculty member, he held a postdoctoral fellowship at the California Institute of Technology and developed one of the first photonic crystal atom-photon interfaces for quantum optics. His research directions at Purdue University span from studying out-of-equilibrium many-body physics using atomic quantum gases to interfacing ultracold atoms with nanophotonic circuits for quantum optics and many-body physics with photon-mediated long-range interactions. He is a recipient of the AFOSR Young Investigator Award and the NSF CAREER award.", "occurrence_notes":null, "guid":"125515-21855231@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/125515", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"411", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Physics","Materials Science","Engineering"], "website":"https:\/\/quantum.umich.edu\/seminars\/fall-2024-seminars", "sponsors":[ { "group_name":"Quantum Research Institute", "group_id":"5043", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" }, { "group_name":"Electrical and Computer Engineering", "group_id":"3153", "website":"http:\/\/www.ece.engin.umich.edu" }, { "group_name":"Applied Physics", "group_id":"3606", "website":"" }, { "group_name":"Department of Chemistry", "group_id":"3761", "website":"https:\/\/lsa.umich.edu\/chem" }, { "group_name":"Astronomy Colloquia", "group_id":"3797", "website":"" }, { "group_name":"Materials Science and Engineering", "group_id":"3942", "website":"" }, { "group_name":"Electrical Engineering and Computer Science", "group_id":"3989", "website":"" }, { "group_name":"Quantum Research Institute", "group_id":"5034", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2024\/09\/event_125515_original-1.jpeg" }, "occurrence_count":1, "first_occurrence":21855231 } , "122384-21848751": { "datetime_modified":"20240620T181506", "datetime_start":"20240912T110200", "datetime_end":"20240912T170000", "has_end_time":1, "date_start":"2024-09-12", "date_end":"2024-09-12", "time_start":"11:02:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Michelle Hinojosa: Logcabins", "occurrence_title":"", "combined_title":"Michelle Hinojosa: Logcabins", "event_subtitle":"", "event_type":"Exhibition", "event_type_id":"7", "description":"Stamps Gallery commissioned Michelle Hinojosa (MFA, 2023) to reimagine the pillars on Division Street that flank the Gallery. Hinojosa has created log cabin quilts to adorn the columns in front of Stamps Gallery. The log cabin quilts traditionally represent the warm hearth at the center of a home. This installation reflects on the interplay between home, placemaking, labor, and intergenerational memories of migration. Rather than quilting cotton designed to softly embrace the body, these quilts are sewn from outdoor grade, UV-resistant polyester. The quilt is an ode to Hinojosa\u2019s grandmother who illegally crossed the US\/Mexico border holding her babies and her quilts. As she and her family drove across the United States to work in the fields of the Salinas Valley, the quilts offered a safe space for her and her family. Hinojosa celebrates their resilience to her grandmother and elders while also drawing attention to precarity and violence experienced by refugees and migrants crossing the US-Mexico border in our present today.\nArtist\u2019s bio:\nMichelle Inez Hinojosa is an artist, educator, and researcher whose work is informed by Indigenous and Latine\/x\/a\/o studies. Born and raised in Texas, she earned her Bachelor of Fine Arts degree in both drawing and painting and art education with a minor in art history at the University of North Texas. She holds a Master of Fine Arts from the University of Michigan. She works with quilting, bead weaving, embroidery, jewelry, transparent film installations, painting, ceramics, and sculpture to honor and explore the history of migration in her family and humanize the current discourse around migration still occurring at the southern border. Alongside her artwork she maintains a writing practice to re-story, re-make, and re-claim the often subordinated narratives of Latinx, Chicanx, Mexican, and Texican peoples. \n\nRecently, Hinojosa was named an inaugural Creative Careers Artist in Residence at the University of Michigan, she has also attended residencies at Mildred's Lane (Pennsylvania), Anderson Ranch Art Center (Aspen, CO) and The Cedars Union (Dallas, TX).
