Interface Roughening in a Hydrodynamic Lattice-Gas Model with Surfactant
arXiv:cond-mat/9606188 · doi:10.1103/PhysRevLett.77.3363
Abstract
Using a hydrodynamic lattice-gas model, we study interface growth in a binary fluid with various concentrations of surfactant. We find that the interface is smoothed by small concentrations of surfactant, while microemulsion droplets form for large surfactant concentrations. To assist in determining the stability limits of the interface, we calculate the change in the roughness and growth exponents and as a function of surfactant concentration along the interface.
