On directed interacting animals and directed percolation

Autor: Knezevic, Milan, Vannimenus, Jean

We study the phase diagram of fully directed lattice animals with nearest-neighbour interactions on the square lattice. This model comprises several interesting ensembles (directed site and bond trees, bond animals, strongly embeddable animals) as sp

Oscillatory Behavior of Critical Amplitudes of the Gaussian Model on a Hierarchical Structure

Autor: Knezevic, Milan, Knezevic, Dragica

We studied oscillatory behavior of critical amplitudes for the Gaussian model on a hierarchical structure presented by a modified Sierpinski gasket lattice. This model is known to display non-standard critical behavior on the lattice under study. The

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

Autor: Elezovic-Hadzic, Suncica, Knezevic, Milan

Publikováno v: Physica A 227 (1996) 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 $n\ge 3$. Using the exact renormalization group method we have been able to obtain the exact

Yang-Lee Edge Singularity on a Class of Treelike Lattices

Autor: Knezevic, Milan, Elezovic-Hadzic, Suncica

Publikováno v: J. Phys. A: Math. Gen. 30 (1997) 2103

The density of zeros of the partition function of the Ising model on a class of treelike lattices is studied. An exact closed-form expression for the pertinent critical exponents is derived by using a couple of recursion relations which have a singul
