Finite-size scaling and universality in the spin-1 quantum XY chain

The spin-1 XY chain in a transverse field is studied using finite-size scaling. The ground state phase diagram displays a paramagnetic, an ordered ferromagnetic and an ordered oscillatory phase. The paramagnetic-ferromagnetic transition line belongs to the universality class of the 2D Ising model. Along this line, universality is confirmed for the finite-size scaling functions of several correl...

Finite-size scaling and universality above the upper critical dimensionality.

According to renormalization theory, Ising systems above their upper critical dimensionality du ­ 4 have classical critical behavior and the ratio of magnetization moments Q ­ km2l2ykm4l has the universal value 0.456947 . . .. However, Monte Carlo simulations of d ­ 5 Ising models have been reported which yield strikingly different results, suggesting that the renormalization scenario is incorr...

Polydispersity Effect and Universality of Finite-Size Scaling Function

We derive an equation for the existence probability Ep for general percolation problem using an analytical argument based on exponential-decay behaviour of spatial correlation function. It is shown that the finite-size scaling function is well approximated by the error function. The present argument explain why it is universal. We use Monte Carlo simulation to calculate Ep for polydisperse cont...

Finite size scaling in CPN-1 models.

Finite size effects in Euclidean CP models with periodic boundary conditions are investigated by means of the 1/N expansion and by Monte Carlo simulations. Analytic and numerical results for magnetic susceptibility and correlation length are compared and found to agree for small volumes. For large volumes a discrepancy is found and explained as an effect of the physical bound state extension. T...

Cluster analysis and finite-size scaling for Ising spin systems.

Based on the connection between the Ising model and a correlated percolation model, we calculate the distribution function for the fraction (c) of lattice sites in percolating clusters in subgraphs with n percolating clusters, f(n)(c), and the distribution function for magnetization (m) in subgraphs with n percolating clusters, p(n)(m). We find that f(n)(c) and p(n)(m) have very good finite-siz...
