In many colloidal suspensions, the micrometer-sized particles behave like hard spheres, but when non-adsorbing polymers are added to the solution a depletion attraction (of entropic origin) is created. Since 60 years the Asakura-Oosawa model, which simply describes the polymers as ideal soft spheres, is an archetypical description for the statistical thermodynamics of such systems, accounting for many features of real colloid-polymer mixtures very well. While the fugacity of the polymers (which… 
Colloid-polymer mixtures under slit confinement.
A NVT molecular dynamic study of colloid-polymer mixtures under slit confinement using the Asakura-Oosawa model for studying colloidal particles, polymer coils, and hard walls as the external confining field, finding that the obtained data fulfill the corresponding states law for a constant H when q is varied.
Phase Diagram and Structure of Mixtures of Large Colloids and Linear Polymers under Good-Solvent Conditions
Efficient Monte Carlo simulations are used to determine the liquid–liquid binodal line of mixtures of hard-sphere colloids and neutral polymers under good-solvent conditions for two values of the
Estimation of the critical behavior in an active colloidal system with Vicsek-like interactions.
Numerically the critical behavior of a modified, active Asakura-Oosawa model for colloid-polymer mixtures is studied, and it is found that the critical point is not located on the rectilinear diameter.

Fluid–fluid coexistence in an athermal colloid–polymer mixture: thermodynamic perturbation theory and continuum molecular-dynamics simulation
Using both theory and continuum simulation, we examine a system comprising a mixture of polymer chains formed from 100 hard-sphere (HS) segments and HS colloids with a diameter which is 20 times that
Structure, thermodynamic properties, and phase diagrams of few colloids confined in a spherical pore.
A system of few colloids confined in a small spherical cavity with event driven molecular dynamics simulations in the canonical ensemble is studied, identifying distinctive qualitative behavior over the thermodynamic plane T - ρ, in a few-particle equivalent to phase diagrams of macroscopic systems.
Structure and Shear Response of Janus Colloid-Polymer Mixtures in Solution.
We investigate the structure and rheological properties of dilute colloid-polymer mixtures at rest and under shear via molecular simulations that take into account hydrodynamic interactions. Mixtures
Influence of solvent quality on depletion potentials in colloid-polymer mixtures.
Monte Carlo simulation is applied to analyze the influence of solvent quality on depletion potentials in mixtures of hard-sphere colloids and nonadsorbing polymer coils, modeled as ellipsoids whose principal radii fluctuate according to random-walk statistics.

Statics and dynamics of colloid-polymer mixtures near their critical point of phase separation: A computer simulation study of a continuous Asakura-Oosawa model.
A new coarse-grained model for the description of liquid-vapor phase separation of colloid-polymer mixtures is proposed, which leads to a coexistence curve that almost coincides with that of the AO model and that the Ising critical behavior of static quantities is reproduced.
Phase coexistence in polydisperse athermal polymer-colloidal mixture.
According to this analysis polydispersity extends the region of the phase instability, shifting the critical point to the lower values of the pressure and density, and causes strong fractionation effects.
Phase behaviour and structure of model colloid-polymer mixtures
We study the phase behaviour and structure of model colloid-polymer mixtures. By integrating out the degrees of freedom of the non-adsorbing ideal polymer coils, we derive a formal expression for the
Monte Carlo simulations of the solid-liquid transition in hard spheres and colloid-polymer mixtures.
Monte Carlo simulations at constant pressure are performed to study coexistence and interfacial properties of the liquid-solid transition in hard spheres and in colloid-polymer mixtures as a one-component Asakura-Oosawa (AO) model.
Depletion induced isotropic-isotropic phase separation in suspensions of rod-like colloids.
The phase boundaries of isotropic-isotropic coexistence both in the bulk and in confinement are estimated and the interfacial tension between the coexisting isotropics phases is analyzed to analyze its power-law behavior on the approach of the critical point.
Phase behavior of athermal colloid-star polymer mixtures.
The results suggest a direct connection between the phase behavior and the scaling regimes of single star structure in the classical Daoud-Cotton (DC) description, and a "low" functionality limit through scaling arguments is defined.
Critical phenomena in colloid-polymer mixtures: interfacial tension, order parameter, susceptibility, and coexistence diameter.
It is found that close to the critical point, the finite size extrapolation of the interfacial tension is most consistent when logarithmic size dependences are ignored.
TOPICAL REVIEW: The physics of a model colloid-polymer mixture
The addition of non-adsorbing polymer to a colloidal suspension induces an interparticle 'depletion' attraction whose range and depth can be 'tuned' independently by altering the polymer's molecular
Critical behavior in colloid-polymer mixtures: theory and simulation.
Computer simulations combined with finite-size scaling analysis confirm the Ising universality and the accuracy of the theory, although some discrepancy in the location of the critical point between one-component and full-mixture description remains.
