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…
New Integrable RG flows with Parafermions
Changrim Ahn, Zoltan Bajnok
We consider irrelevant deformations of massless RSOS scattering theories by an infinite number of higher TTbar_{s+1} operators which introduce extra non-trivial CDD factors between…
Hagedorn singularity in exact U_q(su(2)) S-matrix theories with arbitrary spins
Changrim Ahn, Tommaso Franzini, Francesco Ravanini
Generalizing the quantum sine-Gordon and sausage models, we construct exact S-matrices for higher spin representations with quantum U_q(su(2)) symmetry, which satisfy unitarity, cr…
Nonrelativistic Factorizable Scattering Theory of Multicomponent Calogero-Sutherland Model
Changrim Ahn, Kong-Ju-Bock Lee, Soonkeon Nam
We relate two integrable models in (1+1) dimensions, namely, multicomponent Calogero-Sutherland model with particles and antiparticles interacting via the hyperbolic potential and…
Thermodynamics and Form Factors of Supersymmetric Integrable Field Theories
Changrim Ahn
We study on-shell and off-shell properties of the supersymmetric sinh-Gordon and perturbed SUSY Yang-Lee models using the thermodynamic Bethe ansatz and form factors. Identifying t…
