abstract = {We study the asymmetric zero-range process (ZRP) with L
sites and open boundaries, conditioned to carry an atypical
current. Using a generalized Doob h-transform we compute
explicitly the transition rates of an effective process for
which the conditioned dynamics are typical. This effective
process is a zero-range process with renormalized hopping
rates, which are space dependent even when the original
rates are constant. This leads to non-trivial density
profiles in the steady state of the conditioned dynamics,
and, under generic conditions on the jump rates of the
unconditioned ZRP, to an intriguing supercritical bulk
region where condensates can grow. These results provide a
microscopic perspective on macroscopic fluctuation theory
(MFT) for the weakly asymmetric case: it turns out that the
predictions of MFT remain valid in the non-rigorous limit of
finite asymmetry. In addition, the microscopic results yield
the correct scaling factor for the asymmetry that MFT cannot
predict.},
