Finite-volume form factors in semi-classical approximation
(Elsevier B.V., 2003-10-27)
A semi-classical 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 on a cylinder geometry it provides an ...

Semiclassical scaling functions of sine-Gordon model
(Elsevier B.V., 2004-11-08)
We present an analytic study of the finite size effects in sine-Gordon model, based on the semi-classical quantization of an appropriate kink background defined on a cylindrical geometry. The quasi-periodic kink is realized ...

Solitonic elliptical solutions in the classical XY-model
(ELSEVIER, 2006-10-01)
The solitonic-like solutions predicted by the continuum semi-classical two-dimensional XY-model are investigated using canonical Monte Carlo simulation. In particular, we verify the existence of kink states, and study their ...
