The Bisognano–Wichmann property for asymptotically complete massless QFT

Wojciech Dybalski (TU München)
Mathematics Seminar
Monday, 1 June, 2020, at 16:00-17:00, Zoom (contact Jacob Schach Møller for details)
Description:
A novel algebraic criterion for the Bisognano-Wichmann property of one-particle nets was  recently found by V. Morinelli. In this talk I will explain how to apply this criterion to the  case of massless, integer spin particles using the Mackey subgroup theorem. In the next  step the result will be lifted from the one-particle nets to Haag-Kastler nets using the  assumption of asymptotic completeness. The argument relies on scattering theory of  massless particles due to Buchholz and its recent simplifications. Also ideas from the  massive case, which had been solved by J. Mund, enter into the discussion. The talk is based  on a joint paper with V. Morinelli.
