The universal density-force relation is analyzed and the correspondent universal amplitude ratio Breal is obtained using the massive field theory approach in fixed space dimensions d = 3 up to…
Polymer chains in confined geometries: Massive field theory approach
- D.Romeis, Z.Usatenko
- Physics
- 17 May 2009
The massive field theory approach in fixed space dimensions d = 3 is applied to investigate a dilute solution of long-flexible polymer chains in a good solvent between two parallel repulsive walls,…
Critical adsorption of polymers in a medium with long-range correlated quenched disorder
- Z.Usatenko, A.Ciach
- Materials Science
- 1 August 2003
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 wall by using the…
Surface critical behavior of semi-infinite systems with cubic anisotropy at the ordinary transition
- Z.Usatenko, J.Spalek
- Mathematics
- 12 December 2003
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 to the two-loop…
Influence of long-range correlated surface and near the surface disorder on the process of adsorption of long-flexible polymer chains
- Z.Usatenko, J.-U.Sommer
- Materials Science
- 18 December 2006
The influence of long-range correlated surface and decaying near surface disorder with quenched defects is studied. We consider a correlation function for the defects of the form…
Surface critical behavior of random systems at the special transition
- Z.Usatenko, Chin-Kun Hu
- Physics

The critical behavior at the special surface transition and crossover bevavior from special to ordinary surface transition in semi-infinite n-component anisotropic cubic models are investigated by…
Influence of long-range correlated quenched disorder on the adsorption of long flexible polymer chains on a wall
- Z.Usatenko, A.Ciach
- Materials Science
- 11 May 2004
The process of adsorption on a planar wall of long-flexible polymer chains in the medium with quenched long-range correlated disorder is investigated. We focus on the case of correlations between…
