Consider affine Toda reflection factors and the weak–strong coupling transformation … The reflection factors may correspond to distinct integrable boundary conditions of the same a…

Let $K^+_1(\theta)$ denote the reflection factor for the lowest breather of the $a_2^{(1)}$ affine Toda field theory (ATFT) on a half-line, with rapidity $\theta$. A Neumann bounda…

Let ${\cal A}$ and $\bar{\cal A}$ be the chiral and antichiral descendant algebras, and let $V_a^g(x)$ denote the operator associated with an element $g$ at parameter $a$. The boso…

In two-dimensional integrable quantum field theory, form factors are collections of functions satisfying the bootstrap equations, and every local operator has a set of form factors…
