We study the quenching of the Haldane gap in quasi-one-dimensional systems of weakly coupled spin-1 antiferromagnetic Heisenberg chains. The critical interchain coupling Jc required to stabilize long range magnetic order can be accurately determined from large scale quantum Monte Carlo calculations. Several different geometries of coupled chains are studied, illustrating the dependence of Jc on the coordination of chains. For bipartite geometries, ferromagnetically coupled chains yield similar…

It is shown that it is possible to smoothly connect generally applicable simulation schemes to more restricted loop algorithms that can be constructed only for a limited range of Hamiltonians (where backtracking can be avoided) and the "algorithmic discontinuities" between general and special points (or regions) in parameter space can be eliminated.
