We analyze the conformational properties of polymer macromolecules in solutions in presence of extended structural obstacles of (fractal) dimension ϵd causing the anisotropy of environment. Applying the pruned-enriched ...

A brief review of our recent studies aiming at a better understanding of the scaling behaviour of polymers in disordered environments is given. The main emphasis is on a simple generic model where the polymers are represented ...

We study the scaling laws of diffusion in two-dimensional media with long-range correlated disorder through exact enumeration of random walks. The disordered medium is modelled by percolation clusters with correlations ...
