Attraction and Repulsion between Liquid Droplets over a Liquid-Impregnated Surface

We show that adjacent liquid droplets exhibit long-range attraction and repulsion on an immiscible liquid impregnating a surface when either the drop or the impregnating liquid is volatile. Remarkably, we find that at small times the interaction is attractive, analogous to the “Cheerios effect”, but...
