The use of terahertz radiation, lying in the spectral range 0.1-10 THz (3-330 cm^{-1}), can reveal structural and dynamical information that is not easily accessible by other means.Terahertz vibrational modes are often mediators of technologically important chemical reactions such as the gas capture reaction in clathrates or exchange reactions in metal-organic frameworks. This presentation will review several spectroscopic studies which illustrate some of the ways in which terahertz spectroscopy is being used to study such soft materials.\r\n\r\nBio:\r\nDr. Mittleman received his B.S. in physics from the Massachusetts Institute of Technology in 1988, and his M.S. in 1990 and Ph.D. in 1994, both in physics from the University of California, Berkeley. He then joined AT&T Bell Laboratories as a post-doctoral member of the technical staff, where he built one of the early terahertz time-domain spectrometers for material spectroscopy and imaging. Dr. Mittleman joined the ECE Department at Rice University in September 1996. In 2015, he moved to the School of Engineering at Brown University. His research interests involve the science and technology of terahertz radiation.\u00a0He is a Fellow of the OSA, the APS, and the IEEE, and a Humboldt Research Award winner, and in 2023-2025 he is a Mercator Fellow of the Deutsche Forschungsgemeinschaft. He has recently completed a three-year term as Chair of the\u00a0International Society for Infrared Millimeter and Terahertz Waves.", "occurrence_notes":null, "guid":"129619-21864231@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/129619", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"340", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Physics","Science"], "website":"", "sponsors":[ { "group_name":"CM-AMO Seminars", "group_id":"3801", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21864231 } , "128988-21861980": { "datetime_modified":"20250408T094448", "datetime_start":"20250408T160000", "datetime_end":"20250408T170000", "has_end_time":1, "date_start":"2025-04-08", "date_end":"2025-04-08", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Colloquim Seminar: Stable functions on groups", "occurrence_title":"", "combined_title":"Colloquim Seminar: Stable functions on groups: Gabe Conant (University of Illinois, Chicago)", "event_subtitle":"Gabe Conant (University of Illinois, Chicago)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"In 2011, Malliaris and Shelah proved a strong form of Szemeredi's regularity lemma for the class of \"stable graphs\", which are graphs omitting a certain special subgraph called a \"half-graph\". Using tools from additive combinatorics, Terry and Wolf proved a group theoretic analogue of this result in which finite graphs are replaced by subsets of finite abelian groups. A suitable generalization to arbitrary finite groups was then proved by myself, Pillay, and Terry using model theoretic methods. This talk will focus on an analytic analogue of stability defined for bounded functions on groups. Roughly speaking, the main result of the talk says that if G is amenable, then any stable function on G is almost constant on all translates of a unitary Bohr set in G of bounded complexity. I will also discuss several applications related to Bogolyubobv's Lemma, the Croot-Sisask Lemma, and Folner's Theorem.", "occurrence_notes":null, "guid":"128988-21861980@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/128988", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"1360", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Colloquium Series - Department of Mathematics", "group_id":"4884", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21861980 } , "133758-21873518": { "datetime_modified":"20250312T112541", "datetime_start":"20250408T160000", "datetime_end":"20250408T170000", "has_end_time":1, "date_start":"2025-04-08", "date_end":"2025-04-08", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"EHAP Lecture Series: Alpha Male Replacements in White-Faced Capuchins", "occurrence_title":"", "combined_title":"EHAP Lecture Series: Alpha Male Replacements in White-Faced Capuchins: Meghan Petersdorf, Tulane University", "event_subtitle":"Meghan Petersdorf, Tulane University", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"In primates, male reproductive success is often facilitated by dominance rank. While we have a good understanding of the ultimate benefits that dominance rank provides males, we know less about how male physiology and phenotypes change as males undergo changes in dominance rank. In this seminar, I will discuss our ongoing research on the hormonal, morphological, olfactory, and behavioral correlates of male rank acquisition in white faced-capuchins. Changes in male dominance rank are also associated with high rates of infanticide, which produces extreme sexual conflict. Females have evolved strategies to reduce the occurrence and\/or costs of infanticide to female reproductive success.
