Colloquium Speaker: Lance Dixon (SLAC, Stanford University) Title: The DNA of Particle Scattering Abstract: At the Large Hadron Collider, the copious scattering of quarks and gluons in quantum chromodynamics (QCD) produces Higgs bosons and many backgrounds to searches for new physics. At short distances, scattering in QCD can be evaluated in perturbation theory and leads to highly […]

Active Matter Seminar Speaker: Jayson Paulose, University of Oregon Title: Control of parametric amplification in space-time modulated mechanical metamaterials Abstract: Active mechanical metamaterials harbor acoustic signal processing functionalities that are impossible to achieve in passive structures. Amplifying an elastic wave as it passes through the material is a prominent example, with potential applications in acoustic signal […]
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 […]
