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…

A Systematic Lagrangian Formulation for Quantum and Classical Gravity at High Energies
Ira Z. Rothstein, Michael Saavedra
We derive a systematic Lagrangian approach for quantum gravity in the super-Planckian limit where . The action can be used to calculate to arbitrary accuracy in…

Relations Between Anomalous Dimensions in the Regge Limit
Ira Z. Rothstein, Michael Saavedra
We extend the recent formalism developed for computing rapidity anomalous dimension of form factors using unitarity to the problem of high-energy near forward scattering. By combin…
