Abstract:
We develop a worm algorithm for the O(n) intersecting loop model on the square lattice. We show that our algorithm has little critical slowing-down when 1 ≤ n ≤ 2. We tested this algorithm by investigating the critical properties of the model, for which we determine the critical points and several critical exponents. The present of crossing bonds is found to be irrelevant at the critical branch of the loop model.
