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…

Some aspects of the nonperturbative renormalization of the phi^4 model

J. Kaupuzs

A nonperturbative renormalization of the phi^4 model is considered. First we integrate out only a single pair of conjugated modes with wave vectors +/- q. Then we are looking for t…

Zero range model of traffic flow

J. Kaupuzs, R. Mahnke, R. J. Harris

A multi--cluster model of traffic flow is studied, in which the motion of cars is described by a stochastic master equation. Assuming that the escape rate from a cluster depends on…

Surface tension and interfacial fluctuations in d-dimensional Ising model

J. Kaupuzs

The surface tension of rough interfaces between coexisting phases in 2D and 3D Ising models are discussed in view of the known results and some original calculations presented in t…

Interpretation of experimental data near lambda-transition point in liquid helium

J. Kaupuzs

The recently published experimental data for specific heat C_p of liquid helium in zero gravity conditions very close to the lambda-transition have been discussed. We have shown th…

Polarization kinetics in ferroelectrics with regard to fluctuations

J. Kaupuzs, J. Rimshans, N. F. Smyth

Polarization in ferroelectrics, described by the Landau-Ginzburg Hamiltonian, is considered, based on a multi-dimensional Fokker-Planck equation. This formulation describes the tim…

Critical exponents predicted by grouping of Feynman diagrams in phi^4 model

J. Kaupuzs

Different perturbation theory treatments of the Ginzburg-Landau phase transition model are discussed. This includes a criticism of the perturbative renormalization group (RG) appro…

Nonexistence of the non-Gaussian fixed point predicted by the RG field theory in 4-epsilon dimensions

J. Kaupuzs

The Ginzburg-Landau phase transition model is considered in d=4-epsilon dimensions within the renormalization group (RG) approach. The problem of existence of the non-Gaussian fixe…
