Query: Defect-induced phase transition in the asymmetric simple exclusion
  process   We reconsider the long-standing question of the critical defect hopping rate
$r_c$ in the one-dimensional totally asymmetric exclusion process (TASEP) with
a slow bond (defect). For $r< r_c$ a phase separated state is observed due to
queuing at the defect site whereas for $r\geq r_c$ the defect site has only
local effects on the stationary state of the homogeneous system. Mean-field
theory predicts $r_c=1$ (when hopping rates outside the defect bond are equal
to 1) but numerical investigations seem to indicate $r_c \approx 0.80(2)$. Here
we improve the numerics to show that $r_c > 0.99$ and give strong evidence that
indeed $r_c=1$ as predicted by mean-field theory, and anticipated by recent
theoretical findings.
