Quantum Energy Inequalities

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

General Relativity Seminar Speaker: Chris Fewster, York University Title: Quantum Energy Inequalities Abstract: Many theorems of mathematical relativity, including singularity and positive mass theorems, include the classical energy conditions among their hypotheses. However, matter described by quantum field theory can violate the classical energy conditions and indeed there is no lower bound to the energy […]

Mathematical Aspects of Scattering Amplitudes Lecture Speaker: Tomasz Taylor, Northeastern University Title: Progress in Yang-Mills-Liouville Theory

Love and Naturalness

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Quantum Matter in Mathematics and Physics Seminar Speaker: Mikhail Ivanov (MIT) Title: Love and Naturalness Abstract: Recent progress in gravitational wave astronomy has spurred the development of efficient tools to describe gravitational binary dynamics. One such tool is classical worldline effective field theory (EFT). In the first part of my talk, I will show how to […]

What Observables are Safe to Calculate?

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Quantum Matter in Mathematics and Physics Seminar Speaker: Jesse Thaler, MIT Title: What Observables are Safe to Calculate? Abstract: 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 […]

Symmetry Colloquia – Global Categorical Symmetries

CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

Symmetry Colloquia - Global Categorical Symmetries May 2, 2024 Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Speaker: Clay Còrdova, University of Chicago Title:  Particle-Soliton Degeneracies from Spontaneously Broken Non-Invertible Symmetry Abstract: We study non-invertible topological symmetry operators in massive quantum field theories in (1+1) dimensions. In phases where this symmetry is spontaneously broken […]
