Correlation functions of the XYZ model with a boundary Original Research Article

Integral formulae for the correlation functions of the XYZ model with a boundary are calculated by mapping the model to the bosonized boundary SOS model. The boundary K-matrix considered here coincides with the known general solution of the boundary Yang–Baxter equation. For the case of a diagonal K-matrix, our formulae reproduce the one-point function previously obtained by solving the boundary version of the quantum Knizhnik–Zamolodchikov equation.
