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…

Ising on -- The Affine Conjecture
Richard C. Brower, George T. Fleming, Jin-Yun Lin +2
We review the recent construction \cite{brower2024isingmodelmathbbs2} of the 2d Ising model on a triangulated sphere . Surprisingly, this led to a precise map of the…

Dispersion Relations for Dislocation Modes and their Sensitivity to the Lattice Structure
Jin-Yun Lin, Shashin Pavaskar, Ira Z. Rothstein
In this letter we show that the dispersion relation for the dynamical modes of dislocations ("dislons") in solids is sensitive to the lattice symmetries. In particular, we show tha…
