Semiclassical Particle Spectrum of Double Sine-Gordon Model
G. Mussardo, V. Riva, G. Sotkov
We present new theoretical results on the spectrum of the quantum field theory of the Double Sine Gordon model. This non-integrable model displays different varieties of kink excit…

Finite-Volume Form Factors in Semiclassical Approximation
G. Mussardo, V. Riva, G. Sotkov
A semiclassical approach is used to obtain Lorentz covariant expressions for the form factors between the kink states of a quantum field theory with degenerate vacua. Implemented o…
