Machine-learned many-body potentials from Poisson-Boltzmann calculations on clusters up to 48 colloids show that higher-order interactions reduce cohesion and eliminate broad gas-liquid phase separation, consistent with primitive model pair and triplet potentials.

Many-body attractions do not stabilize gas-liquid phase separation in aqueous dispersions of charged colloids within the Poisson-Boltzmann framework
Machine-learned many-body potentials from Poisson-Boltzmann calculations on clusters up to 48 colloids show that higher-order interactions reduce cohesion and eliminate broad gas-liquid phase separation, consistent with primitive model pair and triplet potentials.
