Query: Stochastic theory of non-equilibrium wetting   We study a Langevin equation describing non-equilibrium depinning and wetting
transitions. Attention is focused on short-ranged attractive
substrate-interface potentials. We confirm the existence of first order
depinning transitions, in the temperature-chemical potential diagram, and a
tricritical point beyond which the transition becomes a non-equilibrium
complete wetting transition. The coexistence of pinned and depinned interfaces
occurs over a finite area, in line with other non-equilibrium systems that
exhibit first order transitions. In addition, we find two types of phase
coexistence, one of which is characterized by spatio-temporal intermittency
(STI). A finite size analysis of the depinning time is used to characterize the
different coexisting regimes. Finally, a stationary distribution of
characteristic triangles or facets was shown to be responsible for the
structure of the STI phase.
