Kink scaling functions in 2D non--integrable quantum field theories
G. Mussardo, V. Riva, G. Sotkov +1
We determine the semiclassical energy levels for the ϕ^4 field theory in the broken symmetry phase on a 2D cylindrical geometry with antiperiodic boundary conditions by quantizing…

Mass Generation in Perturbed Massless Integrable Models
D. Controzzi, G. Mussardo
We extend form-factor perturbation theory to non--integrable deformations of massless integrable models, in order to address the problem of mass generation in such systems. With re…
