Beyond rising levels of economic inequalities recently experienced by many countries, there exist many deep-rooted political and social inequalities that may undermine democratic politics or aid political entrepreneurs leading undemocratic movements to capitalize upon. This roundtable introduces a recently edited volume, Unequal Democracies, that helps untangle the complex relationship between contemporary democracies and inequality along a variety of economic, political, and social dimensions.\r\n \r\nPlease be aware that advance notice is necessary as some accommodations may require more time for the university to arrange.", "occurrence_notes":null, "guid":"124949-21854112@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/124949", "building_id":"1000191", "building_name":"Michigan League", "campus_maps_id":"108", "room":"Room D", "location_name":"Michigan League", "has_livestream":0, "cost":"", "tags":["democracy"], "website":"", "sponsors":[ { "group_name":"Center for Emerging Democracies", "group_id":"3096", "website":"http:\/\/www.ii.umich.edu\/emergingdemocracies" }, { "group_name":"International Institute", "group_id":"1968", "website":"http:\/\/www.ii.umich.edu" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2024\/09\/event_124949_original-2.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2024\/09\/event_124949_original-2.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2024\/09\/event_124949_original-2.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2024\/09\/event_124949_original-2.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2024\/09\/event_124949_original-2.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2024\/09\/event_124949_original-2.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2024\/09\/event_124949_original-2.png" }, "occurrence_count":1, "first_occurrence":21854112 } , "125039-21854246": { "datetime_modified":"20241003T064817", "datetime_start":"20241008T160000", "datetime_end":"20241008T170000", "has_end_time":1, "date_start":"2024-10-08", "date_end":"2024-10-08", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"CM-AMO Seminar |Ultrafast nano-imaging: Probing quantum dynamics in space and time", "occurrence_title":"", "combined_title":"CM-AMO Seminar |Ultrafast nano-imaging: Probing quantum dynamics in space and time: Markus Raschke (University of Colorado)", "event_subtitle":"Markus Raschke (University of Colorado)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Understanding and ultimately controlling the properties of quantum materials and their coupled degrees of freedom will require counteracting the effects of dissipation and dephasing. This necessitates imaging the elementary excitations on their natural time and length scales. To achieve this goal, we developed scanning probe microscopies with ultrafast and shaped laser pulses for multiscale coherent spatio-temporal optical nano-imaging. In corresponding ultrafast movies, we resolve the fundamental quantum dynamics down to the few-femtosecond regime with nanometer spatial resolution. \r\n \r\nSpecifically, in 2D materials and their heterostructures, the emergent electronic, spin, and other quantum properties are controlled by the underlying interlayer coupling and associated charge and energy transfer dynamics. These processes are sensitive to interlayer distance and crystallographic orientation, which are in turn affected by defects, grain boundaries, and other nanoscale heterogeneities. In this talk, I will present the use of adiabatic plasmonic nanofocused four-wave mixing (FWM) [1] to image the coherent electron dynamics in monolayer WSe2 resolving nanoscale heterogeneities in dephasing ranging from T2 < 5 fs to T2 > 60 fs on length scales of 50-100 nm [2]. Further, in combination with Purcell-enhanced nano-cavity clock spectroscopy [3] in WSe2\/graphene heterostructures we identify interlayer energy transfer dynamics at times scales of 350 fs [4]. Beyond the fundamental understanding to the competition between intrinsic and extrinsic effects on excitation lifetimes and coherence, we discover a new regime of nonlinear nano-optics at the interplay of spatial coherence and disorder-induced scattering. \r\n\r\nReferences\r\n[1] T.
