Soft depletion in binary fluids.
We show theoretically that a binary fluid characterized on a mesoscopic scale by purely repulsive short-range interactions without cores possesses an effective attraction between like particles. This "soft depletion effect" is a generic phenomenon driving a mixing-demixing transition in a binary system with pure repulsions.
