Transfer matrix and Monte Carlo tests of critical exponents in Ising model
J. Kaupuzs
The corrections to finite-size scaling in the critical two-point correlation function G(r) of 2D Ising model on a square lattice have been studied numerically by means of exact tra…
Remarks about an "exact" RG theory of Goldstone modes
J. Kaupuzs
A renormalization group (RG) theory of Goldstone mode singularities in the O(n>1)-symmetric phi^4 model is discussed. This perturbative RG theory is claimed to be asymptotically ex…
Transfer matrix and Monte Carlo tests of critical exponents in lattice models
J. Kaupuzs
The corrections to finite-size scaling in the critical two-point correlation function G(r) of 2D Ising model on a square lattice have been studied numerically by means of exact tra…
Longitudinal and transverse Greens functions in phi^4 model below and near the critical point
J. Kaupuzs
We have extended our method of grouping of Feynman diagrams (GFD theory) to study the transverse (G_t) and longitudinal (G_l) Greens functions in phi^4 model below the critical poi…
Monte Carlo test of critical exponents and amplitudes in 3D Ising and phi^4 lattice models
J. Kaupuzs
We have tested the leading correction-to-scaling exponent omega in O(n)-symmetric models on a three-dimensional lattice by analysing the recent Monte Carlo (MC) data. We have found…
Monte Carlo test of critical exponents in 3D Heisenberg and Ising models
J. Kaupuzs
We have tested the theoretical values of critical exponents, predicted for the three--dimensional Heisenberg model, based on the published Monte Carlo (MC) simulation data for the…
