Nonlinear screening, in addition to generating effective many-body interactions, is shown to entail essential corrections to the pair potential and one-body volume energy. Numerical results demonstrate that nonlinear effects can substantially modify effective interactions and thermodynamics of aqueous, low-salt suspensions of highly-charged macroions.4 pages, 4 figuresSoft Condensed MatterStatistical Mechanicstext
