Fluids of spherical molecules with dipolar-like nonuniform adhesion. An analytically solvable anisotropic model
Domenico Gazzillo, Riccardo Fantoni, Achille Giacometti
We consider an anisotropic version of Baxter's model of `sticky hard spheres', where a nonuniform adhesion is implemented by adding, to an isotropic surface attraction, an appropri…
Patchy sticky hard spheres: analytical study and Monte Carlo simulations
Riccardo Fantoni, Domenico Gazzillo, Achille Giacometti +2
We consider a fluid of hard spheres bearing one or two uniform circular adhesive patches, distributed so as not to overlap. Two spheres interact via a ``sticky'' Baxter potential i…
Phase behavior of polydisperse sticky hard spheres: analytical solutions and perturbation theory
Domenico Gazzillo, Achille Giacometti, Riccardo Fantoni
We discuss phase coexistence of polydisperse colloidal suspensions in the presence of adhesion forces. The combined effect of polydispersity and Baxter's sticky-hard-sphere (SHS) p…
Multicomponent adhesive hard sphere models and short-ranged attractive interactions in colloidal or micellar solutions
Domenico Gazzillo, Achille Giacometti, Riccardo Fantoni +1
We investigate the dependence of the stickiness parameters -- where the are the conventional Baxter parameters -- on the solute diameters and…
Phase behavior of weakly polydisperse sticky hard spheres: Perturbation theory for the Percus-Yevick solution
Riccardo Fantoni, Domenico Gazzillo, Achille Giacometti +1
We study the effects of size polydispersity on the gas-liquid phase behaviour of mixtures of sticky hard spheres. To achieve this, the system of coupled quadratic equations for the…
