Semiclassical Energy Levels of Sine-Gordon Model on a Strip with Dirichlet Boundary Conditions
G. Mussardo, V. Riva, G. Sotkov
We derive analytic expressions of the semiclassical energy levels of Sine-Gordon model in a strip geometry with Dirichlet boundary condition at both edges. They are obtained by ini…

Semiclassical Scaling Functions of Sine--Gordon Model
G. Mussardo, V. Riva, G. Sotkov
We present an analytic study of the finite size effects in Sine--Gordon model, based on the semiclassical quantization of an appropriate kink background defined on a cylindrical ge…

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…
