N. Majd et al., Phase transition in an asymmetric generalization of the zero-temperature q-state Potts model - art. no. 046105, PHYS REV E, 6404(4), 2001, pp. 6105
An asymmetric generalization of the zero-temperature q-state Potts model on
a one-dimensional lattice, with and without boundaries, has been studied.
The dynamics of the particle number, and especially the large time behavior
of the system, has been analyzed. In the thermodynamic limit, the system e
xhibits two kinds of phase transitions, a static and a dynamic phase transi
tion.
