Abstract
Single-file diffusion with two species of particles and open boundaries
exhibits much richer non-equilibrium behaviour than well-studied one-component
systems like the asymmetric simple exclusion process and still leads to
surprises. Using rigorous and numerical methods we reveal a self-organized
amplification cycle for fluctuations to be responsible for boundary-induced
spontaneous symmetry breaking in a one-dimensional bulk driven lattice gas model
with two species of particles. Unexpectedly, also in the purely boundary-driven
case (symmetric two-component exclusion) a boundary-induced phase transition
occurs. This phase transition is associated with a structural change of a
boundary layer which is relevant for understanding tracer-exchange in
zeolite grains.
