Dynamic correlations of antiferromagnetic spin-1/2 XXZ chains at arbitrary temperature from complete diagonalization

Klaus Fabricius, Ute Löw, Joachim Stolze

All eigenstates and eigenvalues are determined for the spin- 1/2 $X X Z$ chain $H = 2 J \sum_{i} (S_{i}^{x} S_{i + 1}^{x} + S_{i}^{y} S_{i + 1}^{y} + Δ S_{i}^{z} S_{i + 1}^{z})$ for rings w…
