Abstract

We represent the density matrix of a finite segment of the integrable isotropic spin-1 chain in the thermodynamic limit as a multiple integral. Our integral formula is valid at finite temperature and also includes a homogeneous magnetic field.

Correlation functions of the integrable isotropic spin-1 chain: algebraic expressions for arbitrary temperature

Andreas Klümper, Dominic Nawrath, Junji Suzuki

We derive algebraic formulae for the density matrices of finite segments of the integrable s u (2) isotropic spin-1 chain in the thermodynamic limit. We give explicit results for the 2- and 3-site cases for arbitrary temperature T and zero field. In the zero-temperature limit the correlation functions are given in elementary form in terms of Riemann's zeta function at even integer arguments.

Correlation functions of the integrable spin- s chain ∗

G A P Ribeiro, Andreas Klümper

Abstract We study the correlation functions of su (2) invariant spin- s chains in the thermodynamic limit. We derive nonlinear integral equations for an auxiliary correlation function ω for any spin s and finite temperature T . For the spin-3/2 chain for arbitrary temperature and zero magnetic field we obtain algebraic expressions for the reduced density matrix of two-sites. In the zero temperature limit, the density matrix elements are evaluated analytically and appear to be given in terms of Riemann’s zeta function values of even and odd arguments.

Dynamical correlation functions of theXXZmodel at finite temperature

Kazumitsu Sakai

Combining a lattice path integral formulation for thermodynamics with the solution of the quantum inverse scattering problem for local spin operators, we derive a multiple integral representation for the time-dependent longitudinal correlation function of the spin-1/2 Heisenberg XXZ chain at finite temperature and in an external magnetic field. Our formula reproduces the previous results in the following three limits: the static, the zero-temperature and the XY limits.

The finite temperature density matrix and two-point correlations in the antiferromagneticXXZchain

Frank Göhmann, Nils P Hasenclever, Alexander Seel

We derive finite temperature versions of integral formulae for the two-point correlation functions in the antiferromagnetic XXZ chain. The derivation is based on the summation of density matrix elements characterizing a finite chain segment of length m . On this occasion we also supply a proof of the basic integral formula for the density matrix presented in an earlier publication.

Correlation functions of integrable O(n) spin chains

G A P Ribeiro

We study the correlation functions of the integrable O(n) spin chain in the thermodynamic limit. We addressed the problem of solving functional equations of the quantum Knizhnik Zamolodchikov type for density matrix related to the O(n) spin chain. We give the explicit solution for two-sites density matrix elements for the O(n) which are then evaluated for the n=3,4,…,8 cases at zero temperature.
