title: Short ranged attraction and long ranged repulsion between two solute particles in a subcritical liquid solvent.
abstract: We calculate the effective interaction between two solute particles in a solvent of Lennard-Jones (LJ) particles in two dimensions where the solvent is in the stable liquid phase near the liquid-gas phase coexistence and the solute-solvent interaction is repulsive. Our grand canonical Monte Carlo (GCMC) simulations show that the effective interaction between two solute particles is attractive for separations between the solute particles up to a range of a few nanometres, beyond which the interaction exhibits a marked repulsion. Such an effective interaction stabilizes clusters of nanometre (nm) sizes.
