The thermal deformation of the 2D Tricritical Ising Model gives rise to an exact scattering theory with seven massive excitations based on the exceptional $E_7$ Lie algebra. The high and low temperature phases of this model are related by duality. We will discuss the peculiar features of the self-duality of this model and the possibility to compute exactly the matrix elements (Form Factors) of local and non-local magnetization operators. We employ these Form Factors to compute the exact dynamical structure factors of the theory, a set of quantities with a rich spectroscopy which may be directly tested in future inelastic neutron or Raman scattering experiments.

This talk will give a survey of some of the surprisingly complicated phenomena which emerge when integrability is broken in classical field theories, as seen in the scattering of kink solutions.
Organized by Sebastian Franco (City College, CUNY), Dan Kabat (Lehman College, CUNY), and Vladimir Rosenhaus (CUNY Graduate Center). Sponsored in part by the Initiative for the Theoretical Sciences and by the CUNY doctoral program in Physics.
