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…
