A pattern-formation mechanism driven by attractive forces—previously studied in the context of lateral interactions between adsorbates—is reassessed through a simplified model. In its original version, such a mechanism needed an additional chemical reaction to stabilize the pattern....

Within the reaction–diffusion framework, a one-component system was confined by means of a multiplicative noise into the attraction basin of a patterning attractor in its (infinite-dimensional) configuration space. In this way, inhomogeneities that otherwise would have been “expelled” from...
