Название: The Markov Property Method Applied to lsing Model Calculations
Автор: Baker G.
An efficient method of computation for models possessing the Markov property is set out. We apply this method to the two-dimensional Ising model and report exact computations for up to 10 by 10 models with periodic boundary conditions. We find that critical-point, finite-size rounding is quite large in the renormalized coupling constant, which is not divergent at the critical point, in contrast to the energy, which is also not divergent and has no rounding there. The difference is traced to the continuity of the energy and the discontinuity of the renormalized coupling constant at the critical point.
