Power-law singularities and critical exponents in n-vector models
J. Kaupuzs
Power-law singularities and critical exponents in n-vector models are considered from different theoretical points of view. It includes a theoretical approach called the GFD (group…
Studies of critical phenomena and phase transitions in large lattices with Monte-Carlo based non-perturbative approaches
J. Kaupuzs, J. Rimshans, R. V. N. Melnik
Critical phenomena and Goldstone mode effects in spin models with O(n) rotational symmetry are considered. Starting with the Goldstone mode singularities in the XY and O(4) models,…
Application of thermodynamics to driven systems
R. Mahnke, J. Kaupuzs, J. Hinkel +1
Application of thermodynamics to driven systems is discussed. As particular examples, simple traffic flow models are considered. On a microscopic level, traffic flow is described b…
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…
