Abstract

In this thesis, we review recent progresses on Nonlinear Integral Equation approach to finite size effects in two dimensional integrable quantum field theories, with emphasis to Sine-Gordon/Massive Thirring model and restrictions to minimal models perturbed by Φ_1,3. Exact calculations of the dependence of energy levels on the size are presented for vacuum and many excited states.
