A determination of the low energy parameters of the 2-d Heisenberg antiferromagnet
U. -J. Wiese, H. -P. Ying
We perform numerical simulations of the 2-d antiferromagnetic quantum Heisenberg model using an efficient cluster algorithm. Comparing the finite size and finite temperature effect…

Blockspin Scheme and Cluster Algorithm for Quantum Spin Systems
He-Ping Ying, Uwe-Jens Wiese
We present a numerical study using a cluster algorithm for the 1-d quantum Heisenberg models. The dynamical critical exponent for anti-ferromagnetic chains is su…

Capillary Waves in Binder's Approach to the Interface Tension
U. -J. Wiese
In Binder's approach the reduced interface tension sigma of the Ising model in the broken phase is determined from the finite volume effects of the partition function Z(M) at fixed…
