A smoothed profile method for simulating charged colloidal dispersions Original Research Article

A numerical method is presented for first-principle simulations of charged colloidal dispersions in electrolyte solutions. Utilizing a smoothed profile for colloid-solvent boundaries, efficient mesoscopic simulations are enabled for modeling dispersions of many colloidal particles exhibiting many-body electrostatic interactions. A simple demonstration was performed by calculating stable structures of two-dimensional dispersions, which resulted in the formation of colloidal crystals.
