Inhomogeneous exclusion processes with extended objects: The effect of defect locations
J. J. Dong, B. Schmittmann, R. K. P. Zia
We study the effects of local inhomogeneities, i.e., slow sites of hopping rate , in a totally asymmetric simple exclusion process (TASEP) for particles of size …
Lack of consensus in social systems
I. J. Benczik, S. Z. Benczik, B. Schmittmann +1
We propose an exactly solvable model for the dynamics of voters in a two-party system. The opinion formation process is modeled on a random network of agents. The dynamical nature…
Zero-range process with long-range interactions at a T-junction
A. G. Angel, B. Schmittmann, R. K. P. Zia
A generalized zero-range process with a limited number of long-range interactions is studied as an example of a transport process in which particles at a T-junction make a choice o…
Power Spectra of the Total Occupancy in the Totally Asymmetric Simple Exclusion Process
D. A. Adams, R. K. P Zia, B. Schmittmann
As a solvable and broadly applicable model system, the totally asymmetric exclusion process enjoys iconic status in the theory of non-equilibrium phase transitions. Here, we focus…
Universal properties of population dynamics with fluctuating resources
Sayak Mukherjee, H. K. Janssen, B. Schmittmann
Starting from the well-known field theory for directed percolation, we describe an evolving population, near extinction, in an environment with its own nontrivial spatio-temporal d…
Coarsening of "clouds" and dynamic scaling in a far-from-equilibrium model system
D. A. Adams, B. Schmittmann, R. K. P. Zia
A two-dimensional lattice gas of two species, driven in opposite directions by an external force, undergoes a jamming transition if the filling fraction is sufficiently high. Using…
