This result has only been derived using the path integral in the near-horizon region and relies on many assumptions. We discuss how to derive the T^{3\/2} scaling for the near-extremal rotating BTZ black hole from a calculation in the full black hole background using the Denef-Hartnoll-Sachdev (DHS) formula, which expresses the 1-loop determinant of a thermal geometry in terms of a product over the quasinormal mode spectrum. We also derive the spectral measure for fields of any spin in Euclidean BTZ and use it to provide a new proof of the DHS formula and a new, direct derivation of the BTZ heat kernel. The computations suggest a path to proving the T^{3\/2} scaling for the asymptotically flat 4d Kerr black hole.", "occurrence_notes":null, "guid":"130821-21866921@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/130821", "building_id":"1000208", "building_name":"Randall Laboratory", "campus_maps_id":"133", "room":"3481", "location_name":"Randall Laboratory", "has_livestream":0, "cost":"", "tags":["Brown Bag Seminar","Science","Physics","brown bag"], "website":"", "sponsors":[ { "group_name":"Leinweber Institute for Theoretical Physics", "group_id":"4286", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" }, { "group_name":"HET Brown Bag Series", "group_id":"3805", "website":"" }, { "group_name":"Leinweber Institute for Theoretical Physics Seminars", "group_id":"4311", "website":"" }, { "group_name":"Leinweber Institute for Theoretical Physics Brown Bag Seminars", "group_id":"4865", "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":21866921 } , "130280-21865702": { "datetime_modified":"20241220T163102", "datetime_start":"20250122T120000", "datetime_end":"20250122T140000", "has_end_time":1, "date_start":"2025-01-22", "date_end":"2025-01-22", "time_start":"12:00:00", "time_end":"14:00:00", "time_zone":"America\/Detroit", "event_title":"Industrial and Operations Engineering Building Grand Opening!", "occurrence_title":"", "combined_title":"Industrial and Operations Engineering Building Grand Opening!", "event_subtitle":"", "event_type":"Reception \/ Open House", "event_type_id":"17", "description":"Join us to celebrate the newly renovated U-M Industrial and Operations Engineering (IOE) Building! \r\n\r\nEnjoy refreshments, hear opening remarks from Department Chair Julie Simmons Ivy, witness the ribbon-cutting ceremony and explore the updated spaces with self-guided tours.
