Colloquium: Simon Caron-Huot, McGill University

Abstract: "Please read these lectures last week," the late Sydney Coleman once joked.  Causality is so ingrained in our daily experience that this request seems absurd.  This talk will focus on relativistic causality: the notion that signals cannot move faster than light.  I will review its central role in modern physics and how it leads to surprising properties like analyticity in spin of various physical observables, gives insight on the dynamics of some strongly interacting systems, and restricts potential modifications to Einstein's gravity.

Professor Simon Caron-Huot, McGill will deliver a lecture in his area of research, Quantum Field Theory. He is the recipient of the 2023 Larkin Award for a Junior Researcher. There will be a brief award ceremony before his lecture.
