Nonequilibrium wetting of finite samples
As a canonical model for wetting far from thermal equilibrium we study a Kardar-Parisi-Zhang interface growing on top of a hard-core substrate. Depending on the average growth velocity the model exhibits a non-equilibrium wetting transition which is characterized by an additional surface critical exponent θ. Simulating the single-step model in one spatial dimension we provide accurate numerical...
متن کاملNonequilibrium Wetting
When a nonequilibrium growing interface in the presence of a wall is considered a nonequilibrium wetting transition may take place. This transition can be studied trough Langevin equations or discrete growth models. In the first case, the Kardar-Parisi-Zhang equation, which defines a very robust universality class for nonequilibrium moving interfaces, with a soft-wall potential is considered. W...
متن کاملLine tension at wetting: finite-size effects and scaling functions
We study trie effect of limite system size on trie tension r of a three-phase contact fine. This is especially important in systems with forces that are sufliciently long-ranged for r to diverge in trie thermodynamic Iimit. Near wetting phase transitions we propose an anisotropic finite-size scaling hypothesis, which takes into account trie elfect of thermal capillary-wave fluctuations. Trie si...
متن کاملDepinning and wetting in nonequilibrium systems
We present an extension of equilibrium wetting to nonequilibrium situations particularly suited to systems with anisotropic interactions. Both critical and complete wetting transitions were found and characterized. We have identified a region in the space of parameters (temperature and chemical potential) where the wet and non-wet phases coexist. Emphasis is made on the analogies and difference...
متن کاملNonequilibrium wetting transitions with short range forces.
We analyze within mean-field theory as well as numerically a Kardar-Parisi-Zhang equation that describes nonequilibrium wetting. Both complete and critical wettitng transitions were found and characterized in detail. For one-dimensional substrates the critical weting temperature is depressed by fluctuations. In addition, we have investigated a region in the space of parameters (temperature and ...
