Critical behavior of the restricted primitive model
O. V. Patsahan, I. M. Mryglod
We study the critical behavior of the systems dominated by Coulombic interaction. For this purpose we used the method of collective variables with a reference system. Starting from…
Surface critical behavior of semi-infinite systems with cubic anisotropy at the ordinary transition
Z. Usatenko, J. Spalek
The critical behavior at the ordinary transition in semi-infinite n-component anisotropic cubic models is investigated by applying the field theoretic approach in d=3 dimensions up…
On the criticality of frustrated spin systems with noncollinear order
Yurij Holovatch, Dmytro Ivaneyko, Bertrand Delamotte
We analyze the universal features of the critical behaviour of frustrated spin systems with noncollinear order. By means of the field theoretical renormalization group approach, we…
Where two fractals meet: the scaling of a self-avoiding walk on a percolation cluster
C. von Ferber, V. Blavats'ka, R. Folk +1
The scaling properties of self-avoiding walks on a d-dimensional diluted lattice at the percolation threshold are analyzed by a field-theoretical renormalization group approach. To…
Resonant Enhancement of Inelastic Light Scattering in Strongly Correlated Materials
A. M. Shvaika, O. Vorobyov, J. K. Freericks +1
We use dynamical mean field theory to find an exact solution for inelastic light scattering in strongly correlated materials such as those near a quantum-critical metal-insulator t…
Scaling of star polymers: high order results
V. Schulte-Frohlinde, Yu. Holovatch, C. von Ferber +1
We extend existing renormalization group calculations for the exponents describing scaling of star polymers and polymer networks constituted by chains of different species (the so-…
Influence of quenched dilution on the quasi-long-range ordered phase of the 2d XY model
B. Berche, A. I. Farinas Sanchez, Yu. Holovatch +1
The influence of non magnetic impurities in the 2d XY model is investigated through Monte Carlo (MC) simulations. The general picture of the transition is fully understood from the…
Critical adsorption of polymers in a medium with long-range correlated quenched disorder
Z. Usatenko, A. Ciach
We investigated the influence of short- and long-range correlated quenched disorder introduced into the medium on the process of adsorption of long-flexible polymer chains on a wal…
Phase diagrams of classical spin fluids: the influence of an external magnetic field on the liquid-gas transition
W. Fenz, R. Folk, I. M. Mryglod +1
The influence of an external magnetic field on the liquid-gas phase transition in Ising, XY, and Heisenberg spin fluid models is studied using a modified mean field theory and Gibb…
Dynamics of zz spin correlations in the square-lattice spin-1/2 isotropic XY model
Oleg Derzhko, Taras Krokhmalskii
Using the Jordan-Wigner fermionization in two dimensions we obtain the zz wave vector- and frequency-dependent structure factor for the spin-1/2 isotropic XY model on a spatially a…
Relevance of space anisotropy in the critical behavior of m-axial Lifshitz points
H. W. Diehl, M. A. Shpot, R. K. P. Zia
The critical behavior of -dimensional systems with -component order parameter is studied at an -axial Lifshitz point where a wave-vector instability occurs in an $m…
Crossover between special and ordinary transitions in random semi-infinite Ising-like systems
Z. Usatenko, Chin-Kun Hu
We investigate the crossover behavior between special and ordinary surface transitions in three-dimensional semi-infinite Ising-like systems with random quenched bulk disorder. We…
Green's functions of infinite-U asymmetric Hubbard model: Falicov-Kimball limit
I. V. Stasyuk, O. B. Hera
The asymmetric Hubbard model is used in investigating the lattice gas of the moving particles of two types. The model is considered within the dynamical mean-field method. The effe…
A possible new phase of antagonistic nematogens in a disorienting field
T. G. Sokolovska, M. E. Cates, R. O. Sokolovskii
A simple model is proposed for nematogenic molecules that favor perpendicular orientations as well as parallel ones. (Charged rods, for example, show this antagonistic tendency.) W…
Critical behavior of magnetic systems with extended impurities in general dimensions
V. Blavatska, C. von Ferber, Yu. Holovatch
We investigate the critical properties of d-dimensional magnetic systems with quenched extended defects, correlated in dimensions (which can be considered as the dimensionali…
Critical behaviour of ionic fluids
O. V. Patsahan
Recently we proposed a microscopic approach to the description of the phase behaviour and critical phenomena in binary fluid mixtures. It was based on the method of collective vari…
