Another dimension of Kerr

Regular Seminar Donal O'Connell (Edinburgh U.)

[there will be a 30min pre-seminar for students. For zoom link, please contact s.nagyATqmul.ac.uk] Abstract: Recent work has broadened the scope of scattering amplitudes to include large, classical objects such as the Kerr black hole. This new perspective illuminates surprising aspects of classical gravity, such as the Newman-Janis shift relating Kerr to Schwarzschild. I will describe the connection between amplitudes and classical physics, focussing on the case of Kerr.
