Finite temperature correlation functions from discrete functional equations
Britta Aufgebauer, Andreas Klümper
We present a new approach to the static finite temperature correlation functions of the Heisenberg chain based on functional equations. An inhomogeneous generalization of the n-sit…
Computation of static Heisenberg-chain correlators: Control over length and temperature dependence
Jun Sato, Britta Aufgebauer, Hermann Boos +4
We communicate results on correlation functions for the spin-1/2 Heisenberg-chain in two particularly important cases: (a) for the infinite chain at arbitrary finite temperature $T…
The complete conformal spectrum of a invariant network model and logarithmic corrections
Britta Aufgebauer, Michael Brockmann, Win Nuding +2
We investigate the low temperature asymptotics and the finite size spectrum of a class of Temperley-Lieb models. As reference system we use the spin-1/2 Heisenberg chain with aniso…
Quantum spin chains of Temperley-Lieb type: periodic boundary conditions, spectral multiplicities and finite temperature
Britta Aufgebauer, Andreas Kluemper
We determine the spectra of a class of quantum spin chains of Temperley-Lieb type by utilizing the concept of Temperley-Lieb equivalence with the S=1/2 XXZ chain as a reference sys…
