Root systems and Minimal RG flows to c=1 CFTs
Changrim Ahn, Sara Kostadinovic, Francesco Ravanini
We derive exact massless S-matrices from algebraic root-system geometry and derive thermodynamic Bethe ansatz (TBA) equations that generate minimal renormalization group (RG) flows…

New RG flows between non-Unitary CFTs from exact massless scattering theories
Changrim Ahn, Zoltan Bajnok, Soma Elek
We construct complete solutions of the massless S-matrix bootstrap equations describing a new infinite family of integrable RG flows from the higher-fusion-level minimal models M(3…
