摘要：

We test a multigrid Monte Carlo method for systems with compact variables in the two dimensional XY model on lattices up to 256 X 256. In the vortex phase, using a 10-hit Metropolis updating scheme, we find the integrated autocorrelation time tau-BAR for the magnetic susceptibility scaling with the correlation length xi-like tau-BAR-alpha-xi-1.35(20) in the range-xi almost-equal-to 12-40. In the spin-wave phase critical slowing down appears to be eliminated.
