Abstract
We apply improved Langevin methods with Fourier acceleration to SU(N) x SU(N)/SU(N) spin models in two dimensions for N = 3,4 & 6. We discus s the effect of fourier acceleration and operator improvement techniqu es, measure the fundamental correlation length on lattices upto 128(2) and observe asymptotic scaling in a physical scheme. Bound state mass es are also measured and evidence is found for excited states in all c hannels. Our results are found to be in good agreement with theory.
