Excited TBA Equations I: Massive Tricritical Ising Model
Paul A. Pearce, Leung Chim, Changrim Ahn
We consider the massive tricritical Ising model M(4,5) perturbed by the thermal operator phi_{1,3} in a cylindrical geometry and apply integrable boundary conditions, labelled by t…
The scaling supersymmetric Yang-Lee model with boundary
Changrim Ahn, Rafael I. Nepomechie
We define the scaling supersymmetric Yang-Lee model with boundary as the (1,3) perturbation of the superconformal minimal model SM(2/8) (or equivalently, the (1,5) perturbation of…
Exact solution of the supersymmetric sinh-Gordon model with boundary
Changrim Ahn, Rafael I. Nepomechie
The boundary supersymmetric sinh-Gordon model is an integrable quantum field theory in 1+1 dimensions with bulk N=1 supersymmetry, whose bulk and boundary S matrices are not diagon…
Reflection Amplitudes in Non-Simply Laced Toda Theories and Thermodynamic Bethe Ansatz
Changrim Ahn, P. Baseilhac, V. A. Fateev +2
We study the ultraviolet asymptotics in non-simply laced affine Toda theories considering them as perturbed non-affine Toda theories, which possess the extended conformal symmetry.…
