Numerical Evidence for the Haldane Conjecture
Abstract
The Haldane conjecture, when applied to the Heisenberg O(3) model with a θ term in two dimensions, states that the correlation length diverges when θ approaches π. To verify this conjecture we have numerically simulated the model at imaginary θ and then analytically continued the results to real θ. We have obtained that the value where the model should become critical is θ=3.10(5) in agreement with the expectation.
