Langevin methods for SU(N) chiral models in two dimensions
Description
We apply improved Langevin methods with Fourier acceleration to SU(N)xSU(N)/SU(N) spin models in two dimensions for N=3, 4 and 6. We discuss the effect of Fourier acceleration and operator improvement techniques, measure the fundamental correlation length on lattices up to 1282 and observe asymptotic scaling in a physical scheme. Bound state masses are also measured and evidence is found for excited states in all channels. Our results are found to be in good agreement with theory. (orig.)
