LeClair-Mussardo series for two-point functions in Integrable QFT

Abstract We develop a well-defined spectral representation for two-point functions in relativistic Integrable QFT in finite density situations, valid for space-like separations. The resulting integral series is based on the infinite volume, zero density form factors of the theory, and certain statis...
