Finite-size scaling is used to estimate the critical parameters of the model, confirming universality with the three-dimensional classical Ising model. Critical amplitudes are also estimated for both the energy gap and the ground-state energy.17 pages, 7 figuresStatistical MechanicsFinite-Size Scaling in the transverse Ising Model on a Square Latticetext
