Integrable Quantum Field Theories can be solved exactly using bootstrap techniques based on their elastic and factorisable S -matrix. While knowledge of the scattering amplitudes reveals the exact spectrum of particles and their on-shell dynamics, the expression of the matrix elements of the various...
