Resumen:
We discuss dynamical aspects of an asymmetric version of
assisted diffusion of hard core particles on a ring
studied by G. I. Menon et al. in J. Stat Phys. 86, 1237
(1997). The asymmetry brings in phenomena like kinematic
waves and effects of the Kardar-Parisi-Zhang
nonlinearity, which combine with the feature of strongly
broken ergodicity, a characteristic of the model.
A central role is played by a single nonlocal invariant,
the irreducible string, whose interplay with the driven
motion of reconstituting dimers, arising from the
assisted hopping, determines the asymptotic dynamics
and scaling regimes. These are investigated both
analytically and numerically through sector-dependent
mappings to the asymmetric simple exclusion process.
