DESCRIPTION:Speakers: Giuseppe Mussardo (SISSA)\nThe thermal deformation o
f 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 a
nd the possibility to compute exactly the matrix elements (Form Factors) o
f local and non-local magnetization operators. We employ these Form Fact
ors to compute the exact dynamical structure factors of the theory\, a set
of quantities with a rich spectroscopy which may be directly tested in fu
ture inelastic neutron or Raman scattering experiments.\nhttps://agenda.in
