Determinant Representations for Correlation Functions of Spin-1/2 XXX and XXZ Heisenberg Magnets

arXiv:hep-th/9406133 · doi:10.1007/BF02099470

Abstract

We consider correlation functions of the spin-$\half$ XXX and XXZ Heisenberg chains in a magnetic field. Starting from the algebraic Bethe Ansatz we derive representations for various correlation functions in terms of determinants of Fredholm integral operators.
