Corrections to scaling in the 2D phi^4 model: Monte Carlo results and some related problems
Jevgenijs Kaupuzs, Roderick Melnik
Monte Carlo (MC) simulations have been performed to refine the estimation of the correction-to-scaling exponent in the 2D model, which belongs to one of the most fundamen…
Corrections to finite-size scaling in the 3D Ising model based on non-perturbative approaches and Monte Carlo simulations
J. Kaupuzs, R. V. N. Melnik, J. Rimsans
Corrections to scaling in the 3D Ising model are studied based on non-perturbative analytical arguments and Monte Carlo (MC) simulation data for different lattice sizes L. Analytic…
Corrections to finite--size scaling in the phi^4 model on square lattices
J. Kaupuzs, R. V. N. Melnik, J. Rimsans
Corrections to scaling in the two-dimensional scalar phi^4 model are studied based on non-perturbative analytical arguments and Monte Carlo (MC) simulation data for different latti…
Correlation functions, universal ratios and Goldstone mode singularities in n-vector models
J. Kaupuzs, R. V. N. Melnik, J. Rimsans
Correlation functions in the O(n) models below the critical temperature are considered. Based on Monte Carlo (MC) data, we confirm the fact stated earlier by Engels and Vogt, that…
