Competition of Ferromagnetic and Antiferromagnetic Order in the Spin-1/2 XXZ Chain at Finite Temperature

K. Fabricius, A. Klümper, B. M. McCoy

An analytical study is presented of the crossover in the gapless attractive XXZ chain from antiferromagnetic to ferromagnetic behaviour at low to high temperature, respectively. In…

Spin diffusion and the spin 1/2 XXZ chain at $T = \infty$ from exact diagonalization

Klaus Fabricius, Barry M. McCoy

We study the long time behavior of the zz and xx time dependent autocorrelation function of the spin 1/2 XXZ chain at $T = \infty$ by exact diagonalizations on a chain of 16 sites. W…

Dynamical properties of the compounds CuGeO_3 and α'--NaV_2O_5 at temperatures $T \neq = 0$

K. Fabricius, U. Löw

The dynamical structure factor of the frustrated spin 1/2 Heisenberg model for a series of frustration parameters at finite temperatures is presented. A sharp upper boundary of the…
