Title: The Surprising Simplicity ofScattering Amplitudes
Speaker: Jacob Bourjaily
Institution: Niels Bohr Institute
Place: Room 201, Building 12, YuquanCampus
Time: Dec. 12th,Wednesday, 3:00pm~4:00pm
Abstract:
The way that we understand,teach, and use quantum field theory to make predictions for experiments israpidly changing in order to make the simplicity of our predictions lesssurprising (and hence also easier to compute). Indeed, whether for theoreticalexploration or practical applications, the methods described in textbooks areno longer those being used by experts today.
In this talk, I will describesome of our recent advances that have been made to explain this simplicity andhow they have been used to dramatically extend predictive reach. Much of thisprogress has so far been made for especially simple quantum field theories, butmany of the lessons learned have much wider applicability. I will describe thestatus of these generalizations today, and the concrete roads ahead.
Biography:
Jacob Bourjaily is anAssociate Professor of Physics at the Niels Bohr Institute of the University ofCopenhagen in Denmark. He received his Ph.D. from Princeton University in 2011,under the supervision of Professor Nima Arkani-Hamed at the Institute forAdvanced Study. Afterwards he was elected a Junior Fellow at the HarvardSociety of Fellows, Harvard University, where he stayed until his currentposition in 2014. Jacob is one of the active young pioneers and experts in thestudy of the S-matrix in quantum field theories. He has made significantcontributions to the geometric understanding of perturbative dynamics ofelementary particles merged in recent years, as well as the development of therelated theoretical/computational tools.
