Factorization of multiple integrals representing the density matrix of a finite segment of the Heisenberg spin chain
Herman E. Boos, Frank Göhmann, Andreas Klümper +1
We consider the inhomogeneous generalization of the density matrix of a finite segment of length of the antiferromagnetic Heisenberg chain. It is a function of the temperature…

XX and Ising limits in integral formulae for finite temperature correlation functions of the XXZ chain
Frank Göhmann, Alexander Seel
We consider a multiple integral representation for a one-parameter generating function of the finite temperature - correlation functions of the antiferromagnetic spin-1/2…

Solution of the quantum inverse problem
F. Göhmann, V. E. Korepin
We derive a formula that expresses the local spin and field operators of fundamental graded models in terms of the elements of the monodromy matrix. This formula is a quantum analo…
