As such technologies reach, and even surpass, quantum measurement limits, they can enable new searches for extremely weakly coupled phenomena including gravitational waves, dark matter, and sterile neutrinos.\r\n\r\nAs a demonstration of these techniques, I will describe an initial search for dark matter using an optically levitated nanogram mass sensor, which can exceed the sensitivity of even large underground detectors for certain classes of dark matter in just a few days of operation. If a signal were detected, such sensors may be able to correlate its direction with earth\u2019s motion through the galaxy, allowing definitive confirmation that such a signal arose from dark matter. In addition, I will discuss future applications of such sensors to neutrino physics in a table-top scale experiment. Results from a recent proof-of-principle measurement demonstrate that the force imparted by a single nuclear decay occurring within an optically levitated, dust-sized particle can be detected.", "occurrence_notes":null, "guid":"126099-21856516@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/126099", "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":"Department Colloquia", "group_id":"3804", "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":21856516 } , "128252-21860510": { "datetime_modified":"20241023T114230", "datetime_start":"20241030T150000", "datetime_end":"20241030T170000", "has_end_time":1, "date_start":"2024-10-30", "date_end":"2024-10-30", "time_start":"15:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Grocery Bag Drop-off", "occurrence_title":"", "combined_title":"Grocery Bag Drop-off: Got piles of grocery bags in your dorm?
