Exact time-dependent correlation functions for the symmetric exclusion process with open boundary
J. E. Santos, G. M. Schuetz
As a simple model for single-file diffusion of hard core particles we investigate the one-dimensional symmetric exclusion process. We consider an open semi-infinite system where on…
Non-universal dynamics of staggered non-equilibrium particle systems and Ising chains
R. B. Stinchcombe, J. E. Santos, M. D. Grynberg
Non-universal dynamics is shown to occur in a one-dimensional non-equilibrium system of hard-core particles. The stochastic processes included are pair creation and annihilation (w…
Non-equilibrium critical behavior of O(n)-symmetric systems: Effect of reversible mode-coupling terms and dynamical anisotropy
Uwe C. Täuber, Jaime E. Santos, Zoltán Rácz
Phase transitions in non-equilibrium steady states of O(n)-symmetric models with reversible mode couplings are studied using dynamic field theory and the renormalization group. The…
Branching-annihilating random walks in one dimension: Some exact results
K. Mussawisade, J. E. Santos, G. M. Schütz +1
We derive a self-duality relation for a one-dimensional model of branching and annihilating random walkers with an even number of offsprings. With the duality relation and by deriv…
The duality relation between Glauber dynamics and the diffusion-annihilation model as a similarity transformation
J. E. Santos
In this paper we address the relationship between zero temperature Glauber dynamics and the diffusion-annihilation problem in the free fermion case. We show that the well-known dua…
