摘要：

We consider zero temperature correlation functions of the spin-1/2 XXZ Heisenberg chain in the critical regime -1 < Delta less than or equal to 1 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.
