Fermi Liquid Fixed Point Deformations due to Codimension Two Defects
Jin-Yun Lin, Ira Z. Rothstein
We show that codimension-two defects in Fermi liquids deform the renormalization group flow via a marginally relevant coupling. The mechanism for generating the flow is distinct fr…

Analytic structure of the high-energy gravitational amplitude: multi-H diagrams and classical 5PM logarithms
Francesco Alessio, Vittorio Del Duca, Riccardo Gonzo +3
We investigate the high-energy, small-angle limit of two-body gravitational scattering. Using power counting arguments and dispersion relations in an effective field theory for the…
