Binary mixtures of hard spheres with different diameters and square-well attraction between different particles are studied by theory and Monte Carlo simulations. In our mesoscopic theory, local fluctuations of the volume fraction of the two components are taken into account. Semi-quantitative agreement between the simulation and theoretical results is obtained, except from very small distances. The correlation functions exhibit exponentially damped oscillations, with the period determined by… 
Adsorption in Mixtures with Competing Interactions
It is found that alternating layers or bilayers of particles of the two components are formed, but the number of the adsorbed layers, their orientation and the ordered patterns formed inside these layers could be quite different for different substrates and gas density.
Mesoscopic Inhomogeneities in Concentrated Electrolytes
A mesoscopic theory for water-in-salt electrolytes combining density functional and field-theoretic methods is developed in order to explain the unexpectedly large period of the oscillatory decay of


Decay of correlation functions in hard-sphere mixtures: structural crossover.
It is shown that structural crossover also manifests itself in the intermediate range behavior of the pair correlation functions and the relevance of this observation for real (colloidal) mixtures is commented on.
Effects of fluctuations on correlation functions in inhomogeneous mixtures
Approximate expressions for correlation functions in binary inhomogeneous mixtures are derived in a framework of the mesoscopic theory [Ciach A., Mol. Phys., 2011, {\textbf{109}}, 1101]. Fluctuation
Homogeneous and inhomogeneous hard-sphere mixtures: manifestations of structural crossover
Various manifestations of structural crossover in the properties of a binary mixture of hard-spheres are studied. For homogeneous mixtures that are sufficiently asymmetric, there is a crossover line
Direct observation in 3d of structural crossover in binary hard sphere mixtures.
Using particle-resolved colloid experiments in 3d it is demonstrated that crossover exists and that its location in the phase diagram is in quantitative agreement with the results of both theory and Monte-Carlo simulations.

A stability analysis of the primitive model of ionic systems with respect to periodic ordering using the collective variables-based theory is performed and the character of the dominant fluctuations along the λ lines is analyzed.
Self-assembly in a model colloidal mixture of dimers and spherical particles.
The structure of a dilute mixture of amphiphilic dimers and spherical particles, a model relevant to the problem of encapsulating globular "guest" molecules in a dispersion, is investigated, suggesting that in this case clusters are metastable with respect to crystal-vapor separation.
Mesoscopic theory for inhomogeneous mixtures
Mesoscopic density functional theory for inhomogeneous mixtures of spherical particles is developed in terms of mesoscopic volume fractions by a systematic coarse-graining procedure starting form
Correlation functions in an ionic liquid at coexistence with an ionic crystal: results of the Brazovskii-type field theory
Correlation functions in the restricted primitive model are calculated within a field-theoretic approach in the one-loop self-consistent Hartree approximation. The correlation functions exhibit
Cluster formation in binary fluids with competing short-range and long-range interactions
Abstract The equilibrium phase behaviour of a model binary fluid is investigated through Monte Carlo simulations and by developing a molecular thermodynamic model. Both fluid components interact
Effect of mesoscopic fluctuations on equation of state in cluster-forming systems
Equation of state for systems with particles self-assembling into aggregates is derived within a mesoscopic theory combining density functional and field-theoretic approaches. We focus on the effect
