Simulational study for the crossover in the generalized contact process with diffusion
W. G. Dantas, M. J. de Oliveira, J. F. Stilck
In a recent work, Dantas and Stilck studied a model that generalizes the contact process model with diffusion. Our approach, based on the supercritical expansion, showed that for a…

A general creation-annihilation model with absorbing states
Wellington G. Dantas, Armando Ticona, Jurgen F. Stilck
A one dimensional non-equilibrium stochastic model is proposed where each site of the lattice is occupied by a particle, which may be of type A or B. The time evolution of the mode…

Semiflexible polymer in a strip
Jurgen F. Stilck
We study the thermodynamic properties of a semiflexible polymer confined inside strips of widths L<=9 defined on a square lattice. The polymer is modeled as a self-avoiding walk an…
