What can be learnt from the nonperturbative renormalization group?

Delamotte, B.; Canet, L. (Condensed Matter Physics, 2005)

We point out some limits of the perturbative renormalization group used in statistical mechanics both at and out of equilibrium. We argue that the non-perturbative renormalization group formalism is a promising candidate to ...
Phenomenological study of spin-triplet ferromagnetic superconductors

Shopova, D.V.; Tsvetkov, T.E.; Uzunov, D.I. (Condensed Matter Physics, 2005)

Unconventional superconductivity with spin-triplet Cooper pairing is reviewed based on the quasi-phenomenological Ginzburg-Landau theory. The superconductivity, in particular, the mixed phase of coexistence of ...
Critical thermodynamics of two-dimensional N-vector cubic model in the five-loop approximation

Calabrese, P.; Orlov, E.V.; Pakhnin, D.V.; Sokolov, A.I. (Condensed Matter Physics, 2005)

The critical behavior of the two-dimensional N-vector cubic model is studied within the field-theoretical renormalization-group (RG) approach. The β functions and critical exponents are calculated in the five-loop ...
Monte Carlo studies of critical behaviour of systems with long-range correlated disoder

Prudnikov, V.V.; Prudnikov, P.V.; Dorofeev, S.V.; Kolesnikov, V.Yu. (Condensed Matter Physics, 2005)

Monte Carlo simulations of the short-time dynamic behaviour are reported for three-dimensional Ising model and XY-model with long-range spatially correlated disorder at criticality, in the case corresponding to linear ...
Scaling in public transport networks

von Ferber, C.; Holovatch, Yu.; Palchykov, V. (Condensed Matter Physics, 2005)

We analyse the statistical properties of public transport networks. These networks are defined by a set of public transport routes (bus lines) and the stations serviced by these. For larger networks these appear to possess ...
The strong-weak coupling symmetry in 2D Φ⁴ field models

Shalaev, B.N. (Condensed Matter Physics, 2005)

It is found that the exact beta-function β(g) of the continuous 2D gΦ⁴ model possesses two types of dual symmetries, these being the KramersWannier (KW) duality symmetry and the strong-weak (SW) coupling symmetry f(g), ...
Toy models of developed turbulence

Hnatich, M.; Jurcisin, M.; Repasan, M. (Condensed Matter Physics, 2005)

We have investigated the advection of a passive scalar quantity by incompressible helical turbulent flow within the framework of extended Kraichnan model. Turbulent fluctuations of velocity field are assumed to have the ...
On the thermodynamic properties of the generalized Gaussian core model

Mladek, B.M.; Fernaud, M.J.; Kahl, G.; Neumann, M. (Condensed Matter Physics, 2005)

We present results of a systematic investigation of the properties of the generalized Gaussian core model of index n. The potential of this system interpolates via the index n between the potential of the Gaussian ...
Criticality of the random-site Ising model: Metropolis, Swendsen-Wang and Wolff Monte Carlo algorithms

Ivaneyko, D.; Ilnytskyi, J.; Berche, B.; Holovatch, Yu. (Condensed Matter Physics, 2005)

We apply numerical simulations to study of the criticality of the 3D Ising model with random site quenched dilution. The emphasis is given to the issues not being discussed in detail before. In particular, we attempt a ...
High-temperature series expansions for random Potts models

Hellmund, M.; Janke, W. (Condensed Matter Physics, 2005)

We discuss recently generated high-temperature series expansions for the free energy and the susceptibility of random-bond q-state Potts models on hypercubic lattices. Using the star-graph expansion technique, ...
Order of superconductive phase transition

Kleinert, H. (Condensed Matter Physics, 2005)

On the occasion of Reinhard Folk’s 60th birthday, I give a brief review of the theoretical progress in understanding the critical properties of superconductors. I point out the theoretical difficulties in finding a ...
Interacting N-vector order parameters with O(N) symmetry

Pelissetto, A.; Vicari, E. (Condensed Matter Physics, 2005)

We consider the critical behavior of the most general system of two Nvector order parameters that is O(N) invariant. We show that it may have a multicritical transition with enlarged symmetry controlled by the chiral O(2) ...
Fluctuations and criticality (dedicated to Reinhard Folk on his 60th birthday)

Iro, H.; Holovatch, Yu.; Mryglod, I.; von Ferber, C. (Condensed Matter Physics, 2005)
Is classical mechanics based on Newton’s Laws or Eulers analytical equations?

Iro, H. (Condensed Matter Physics, 2005)

In an example I illustrate how my picture of physics is enriched due to my frequent conversations with Reinhard Folk. The subject is: Who wrote down the basic equations of motion of classical mechanics for the first time? ...
Novel phase transition in two-dimensional xy-models with long-range interaction

Maier, P.G.; Schwabl, F. (Condensed Matter Physics, 2005)

The purpose of this article is to give an overview of results concerning ordering and critical properties of two-dimensional ferromagnets including the dipolar interaction. We investigate a two-dimensional xy-model ...
Ising antiferromagnet with mobile, pinned, and quenched defects

Selke, W.; Holtschneider, M.; Leidl, R. (Condensed Matter Physics, 2005)

Motivated by recent experiments on (Sr,Ca,La)₁₄Cu₂₄O₄₁, a two-dimensional Ising antiferromagnet with mobile, locally pinned and quenched defects is introduced and analyzed using mainly Monte Carlo techniques. The ...
Wavevector- and frequency-dependent shear viscosity of water: the modified collective mode approach and molecular dynamics calculations

Omelyan, I.P.; Mryglod, I.M.; Tokarchuk, M.V. (Condensed Matter Physics, 2005)

The transverse momentum time autocorrelation functions and wavevectorand frequency-dependent shear viscosity are calculated for an interaction site model of water using a modified collective mode approach and molecular ...
Random Ising model in three dimensions: theory, experiment and simulation – a difficult coexistence

Berche, B.; Berche, P.E.; Chatelain, C.; Janke, W. (Condensed Matter Physics, 2005)

We discuss different approaches to the study of the effect of disorder in the three-dimensional Ising model. From the theoretical point of view, renormalization group calculations provide quite accurate results. ...
