Is finite-size scaling universal for Ising models?

摘要

The sensitivity on shape and boundaries at the Curie point of the universal critical ratio (LM2)-M-d/chi for the Ising model is confirmed by a comparison of square and rectangular lattices. Tests with three different algorithms give the same results for the universal critical ratio on various lattice types and always the same dependence on the system's aspect ratio. [References: 5]
