In the case of strictly convex and smooth bounded planar domains, the problem is very much open. One technique for studying the inverse spectral problem is via the wave trace, a distribution with singular support contained in the length spectrum. The length spectrum is the collection of lengths of closed geodesics, which for planar domains are just periodic billiard orbits. A dual object to study is the resolvent (of the Laplacian), whose trace asymptotics are related via the Payley-Wiener theorem to singularities of the wave trace. In this talk, we introduce the Balian-Bloch-Zelditch method of constructing a parametrix for the resolvent trace via layer potentials. The result is an oscillatory integral to which one can apply the method of stationary phase. A novel feature is the organization of stationary phase coefficients by using graph theory and Feynman diagrams. The resulting formulas can be used to match Maslov indices of orbits and produce cancellations in the wave trace, which shows that the length spectrum and the Laplace spectrum are inherently distinct objects, at least insofar as the wave trace is concerned.", "occurrence_notes":null, "guid":"119982-21843897@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/119982", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"4088", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Differential Equations Seminar - Department of Mathematics", "group_id":"4888", "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":21843897 } , "108410-21819552": { "datetime_modified":"20240109T155914", "datetime_start":"20240404T160000", "datetime_end":"20240404T180000", "has_end_time":1, "date_start":"2024-04-04", "date_end":"2024-04-04", "time_start":"16:00:00", "time_end":"18:00:00", "time_zone":"America\/Detroit", "event_title":"EIHS Lecture: Promissory Talk and the Limits of Historical Imagination", "occurrence_title":"", "combined_title":"EIHS Lecture: Promissory Talk and the Limits of Historical Imagination: Jolyon Baraka Thomas (University of Pennsylvania)", "event_subtitle":"Jolyon Baraka Thomas (University of Pennsylvania)", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"This lecture uses the concept of promissory talk to critically analyze one way of thinking \u201cagainst history.\u201d Promissory talk is a future-oriented version of counterfactual speculation.

In this talk, I will offer two vignettes on our work developing and applying approaches to predict and understand spectral features in molecular and nanomaterial systems. In the molecular world, I will show how our recent advances in condensed phase spectroscopy enable us to decipher a long-standing puzzle in porphyrin photophysics: why and how do the Q bands involved in energy transfer in photosynthesis and artificial energy conversion split? In the nanomaterial world, I will highlight how we have been able to demonstrate how the unusual photophysics of atomically thin 2D materials enables hot carrier extraction for photocatalysis. Then, I will illustrate how addressing the challenge of hot carrier extraction enabled us to develop a simple scheme to disentangle the signals of exotic quasiparticles that explain the tunability of the optical behavior of these materials as a function of potential, laser fluence, and time.", "occurrence_notes":null, "guid":"109302-21821367@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/109302", "building_id":"1000158", "building_name":"Chemistry Dow Lab", "campus_maps_id":"34", "room":"1640", "location_name":"Chemistry Dow Lab", "has_livestream":0, "cost":"", "tags":["Chemistry","Physical Chemistry","Science"], "website":"https:\/\/www.colorado.edu\/chemistry\/andres-montoya-castillo", "sponsors":[ { "group_name":"Department of Chemistry", "group_id":"3761", "website":"https:\/\/lsa.umich.edu\/chem" }, { "group_name":"Physical Chemistry", "group_id":"4390", "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":21821367 } , "120739-21845199": { "datetime_modified":"20240328T071812", "datetime_start":"20240404T160000", "datetime_end":"20240404T170000", "has_end_time":1, "date_start":"2024-04-04", "date_end":"2024-04-04", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Interdisciplinary QC-CM Seminar | Bridging Hubbard and quantum Hall physics in twisted bilayer graphene", "occurrence_title":"", "combined_title":"Interdisciplinary QC-CM Seminar | Bridging Hubbard and quantum Hall physics in twisted bilayer graphene: Eslam Khalaf (Harvard University)", "event_subtitle":"Eslam Khalaf (Harvard University)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Early on it was noticed that twisted bilayer graphene has elements in common with two paradigmatic examples of strongly correlated physics: Hubbard physics and quantum Hall physics. Indeed, twisted bilayer graphene hosts flat topological bands, but these bands host concentrated charge density, experimental signs of fluctuating magnetism, and signs of unconventional superconductivity. The emergence of fluctuating moments is particularly surprising, as localized Wannier states do not exist in topological bands. I will discuss a model for the twisted bilayer graphene flat bands that centers the concentration of charge density and, relatedly, the concentration of Berry flux. After establishing good quantitative agreement with more microscopic models, I will show how the model hosts parametrically decoupled flavor moments. These flavor moments are tied to Wannier states that are power-law delocalized, with infinite localization length, that nonetheless have parametrically small overlap with each other.
