  sine-Gordon model   We obtain nonperturbative results on the sine-Gordon model using the lattice
field technique. In particular, we employ the Fourier accelerated hybrid Monte
Carlo algorithm for our studies. We find the critical temperature of the theory
based autocorrelation time, as well as the finite size scaling of the
"thickness" observable used in an earlier lattice study by Hasenbusch et al.
