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 […]

Colloquium Speaker: Sarah Harrison (Northeastern University) Title: Liouville Theory and Weil-Petersson Geometry Abstract: Two-dimensional conformal field theory is a powerful tool to understand the geometry of surfaces. Liouville conformal field theory in the classical (large central charge) limit encodes the geometry of the moduli space of Riemann surfaces. I describe an efficient algorithm to compute […]
CMSA Member Seminar Speaker: Sergiy Verstyuk Title: On using ML for Economics Abstract: I will introduce some tools from the field of machine learning and discuss how they can be leveraged to get a fresh perspective on economics.
General Relativity Seminar Speaker: Albert Law, Stanford Title: Real-time observables in horizon thermodynamics Abstract: Euclidean black hole 1-loop determinants have recently been shown to compute a renormalized thermal canonical partition function for free fields in Lorentzian signature. A key ingredient is a 'quasinormal mode (QNM) character', whose Fourier transform equals the renormalized spectral density of the single-particle […]
