Monte Carlo studies of universal critical amplitudes for the three-dimensional Ising model: Correlation length and renormalized coupling

We report Monte Carlo studies of the finite-size second-moment correlation length and renormalized coupling at criticality for the three-dimensional Ising model on body-centered-cubic lattices. The related finite-size scaling amplitudes are estimated and compared with the simple-cubic lattice results of recent extensive simulations. The amplitudes agreed within statistical uncertainty and are consistent with finite-size-scaling arguments for universality.
