Abstract
The properties of S = 1 Heisenberg antiferromagnetic chains are completely different with those of S = 1/2 Heisenberg antiferromagnetic chains. Numerical methods such as projector Monte Carlo method, world line Monte Carlo method and exact diagonalization method are very useful for the investigation of these systems.KeywordsGround State EnergyWorld LineElementary ExcitationExact DiagonalizationVariational Wave FunctionThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
