Adsorption in a model of interacting branched polymers on a fractal lattice

Vujić, Dragan; Knežević, Milan - In: Physica A: Statistical Mechanics and its Applications 260 (1998) 1, pp. 1-10

We have studied a model of self-interacting branched polymers on the three-dimensional Sierpinski gasket lattice, in the presence of an attractive impenetrable fractal boundary. Using an exact renoramlization group approach, we have determined the phase diagram boundaries of this model, and its...

Critical exponents of surface-interacting self-avoiding walks on a family of truncated n-simplex lattices

Elezović-Hadžić, Sunčica; Knežević, Milan - In: Physica A: Statistical Mechanics and its Applications 227 (1996) 3, pp. 213-233

We study the critical behavior of surface-interacting self-avoiding random walks on a class of truncated simplex lattices, which can be labeled by an integer n ⩾ 3. Using the exact renormalization group method we have been able to obtain the exact values of various critical exponents for all...

New simple properties of a few irregular systems

Sapoval, B.; Andrade, J.S.; Baldassarri, A.; Desolneux, A. - In: Physica A: Statistical Mechanics and its Applications 357 (2005) 1, pp. 1-17

results are related to dynamical and static properties of gradient percolation. Firstly, it is shown that the transient … regimes which lead to self-organized gradient percolation due to corrosion do not scale like gradient percolation itself …
