# Finite volume form factors and correlation functions at finite temperature

@article{Pozsgay2009FiniteVF, title={Finite volume form factors and correlation functions at finite temperature}, author={Bal'azs Pozsgay}, journal={arXiv: High Energy Physics - Theory}, year={2009} }

In this thesis we investigate finite size effects in 1+1 dimensional integrable QFT. In particular we consider matrix elements of local operators (finite volume form factors) and vacuum expectation values and correlation functions at finite temperature. In the first part of the thesis we give a complete description of the finite volume form factors in terms of the infinite volume form factors (solutions of the bootstrap program) and the S-matrix of the theory. The calculations are correct to… Expand
