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…
