The non-equilibrium dynamics of the kinetic spherical model with a non-conserved order-parameter, quenched to T≤T<Subscript>c</Subscript> from a fully disordered initial state, is studied at its upper critical dimension d=d<Superscript>*</Superscript>=4. In the scaling limit where both the waiting time s and the observation time t are large...</superscript></subscript>

The one-dimensional Domany-Kinzel cellular automaton is investigated by two numerical approaches: (i) the spontaneous-search method, which is a method appropriated for a search of criticality; (ii) short-time dynamics. Both critical frontiers of the system are investigated, namely, the one...

We study the lattice gas with nearest-neighbor exclusion on the square lattice and Kawasaki (hopping) dynamics, under the influence of a nonuniform drive, via Monte Carlo simulation. The drive, which favors motion along the +x direction and inhibits motion in the opposite direction, varies...
