Pizzo)\n
\nI will discuss some recent progress on infrared problems in non-perturbative approaches to\nQED. First, I will explain the general distinction between the `infraparticle\u00e2 and `infravacuum\u00e2 picture\nof the electron which pertains to the existence resp. non-existence of the spacelike asymptotic flux of\nthe electric field. On this basis the problem of electron-photon scattering will be discussed both in\nmodels of non-relativistic QED and in the setting of algebraic QED.\n
\nOn the infraparticle side, we will revisit the Faddeev-Kulish approach, theory of particle weights and\nthe problem of velocity superselection. On the infravacuum side the talk will cover Kraus-Polley-\nReents representations and the Buchholz-Roberts approach. If time allows, relations to a current trend\nin high-energy physics triggered by the works of A. Strominger et al. on the Weinberg's soft-photon\ntheorems will be discussed.","@language":"en"}],"DigitalResourceOriginalRecord":[{"@value":"https:\/\/circle.library.ubc.ca\/rest\/handle\/2429\/68716?expand=metadata","@language":"en"}],"Extent":[{"@value":"53.0","@language":"en"}],"FileFormat":[{"@value":"video\/mp4","@language":"en"}],"FullText":[{"@value":"","@language":"en"}],"IsShownAt":[{"@value":"10.14288\/1.0376882","@language":"en"}],"Language":[{"@value":"eng","@language":"en"}],"Notes":[{"@value":"Author affiliation: Technical University Munich","@language":"en"}],"PeerReviewStatus":[{"@value":"Unreviewed","@language":"en"}],"Provider":[{"@value":"Vancouver : University of British Columbia Library","@language":"en"}],"Publisher":[{"@value":"Banff International Research Station for Mathematical Innovation and Discovery","@language":"en"}],"Rights":[{"@value":"Attribution-NonCommercial-NoDerivatives 4.0 International","@language":"en"}],"RightsURI":[{"@value":"http:\/\/creativecommons.org\/licenses\/by-nc-nd\/4.0\/","@language":"en"}],"ScholarlyLevel":[{"@value":"Postdoctoral","@language":"en"}],"Series":[{"@value":"BIRS Workshop Lecture Videos (Banff, Alta)","@language":"en"}],"Subject":[{"@value":"Mathematics","@language":"en"},{"@value":"Quantum theory","@language":"en"},{"@value":"Functional analysis","@language":"en"},{"@value":"Mathematical physics","@language":"en"}],"Title":[{"@value":"Infrared problems in QED: Some topics of current research","@language":"en"}],"Type":[{"@value":"Moving Image","@language":"en"}],"URI":[{"@value":"http:\/\/hdl.handle.net\/2429\/68716","@language":"en"}],"SortDate":[{"@value":"2018-07-31 AD","@language":"en"}],"@id":"doi:10.14288\/1.0376882"}
