SUMMARY:Discrete geometry and the modular bootstrap
DESCRIPTION:Quantum Matter in Mathematics and Physics Seminar \nSpeaker: Henry Cohn (MIT and Microsoft) \nTitle: Discrete geometry and the modular bootstrap \nAbstract: In this talk\, I’ll discuss the remarkable connections between the modular bootstrap and sphere packing or ground state problems discovered by Hartman\, Mazáč\, and Rastelli in 2019\, with a focus on opportunities for further progress.

SUMMARY:What Observables are Safe to Calculate?
DESCRIPTION:Quantum Matter in Mathematics and Physics Seminar \nSpeaker: Jesse Thaler\, MIT \nTitle: What Observables are Safe to Calculate? \nAbstract: In collider physics\, perturbative quantum field theory is the workhorse framework for computing theoretical predictions to compare to experimental measurements. An observable is called “safe” if its cross section can be predicted order-by-order in perturbation theory with controlled non-perturbative corrections. In this talk\, I show that naive definitions of “safety” are inadequate to determine which observable are perturbatively calculable. I then argue for a more refined definition of safety based on principles from optimal transport theory.
