For binary fluid mixtures of spherical particles in which the two species are sufficiently different in size, the dominant wavelength of oscillations of the pair correlation functions is predicted to change from roughly the diameter of the large species to that of the small species along a sharp crossover line in the phase diagram [C. Grodon et al., J. Chem. Phys. 121, 7869 (2004)]. Using particle-resolved colloid experiments in 3d we demonstrate that crossover exists and that its location in…

Connecting Packing Efficiency of Binary Hard Sphere Systems to Their Intermediate Range Structure
Using computed x-ray tomography we determine the three dimensional (3d) structure of binary hard sphere mixtures as a function of composition and size ratio of the particles, q. Using a recently
Thermodynamic behavior of binary mixtures of hard spheres: Semianalytical solutions on a Husimi lattice built with cubes.
We study binary mixtures of hard particles, which exclude up to their kth nearest neighbors (kNN) on the simple cubic lattice and have activities z_{k}. In the first model analyzed, point particles
Structure factors in a two-dimensional binary colloidal hard sphere system
ABSTRACT Hard disks are one of the simplest interacting many-body model system in two dimensions (2D). Here, we present a comprehensive set of measurements of the static structure factors for
Structural crossover in a model fluid exhibiting two length scales: Repercussions for quasicrystal formation.
TLDR
It is argued that identifying and following a crossover line in the phase diagram towards higher densities where the solid phase(s) occur is a good strategy for finding quasicrystals in a wide variety of systems.
Structural properties of additive binary hard-sphere mixtures. II. Asymptotic behavior and structural crossovers.
TLDR
The so-called rational-function approximation method and an approach combining accurate molecular dynamics simulation data, the pole structure representation of the total correlation functions, and the Ornstein-Zernike equation are considered are considered.
Screening Lengths in Ionic Fluids.
TLDR
This analysis provides an explanation for the recently observed discontinuous change in the structural force across a thin film of ionic liquid-solvent mixtures as the composition is varied, as well as reframes recent debates about the screening length in concentrated electrolytes.
Structural properties of additive binary hard-sphere mixtures.
TLDR
A very good overall agreement between the results of the present scheme and those of the RFA is found, suggesting that the latter (which is an improvement over the PY approximation) can safely be used to predict reasonably well the long-range behavior of the correlation functions of additive binary hard-sphere mixtures.
Integral equation theory of thermodynamics, pair structure, and growing static length scale in metastable hard sphere and Weeks-Chandler-Andersen fluids.
We employ the Ornstein-Zernike integral equation theory with the Percus-Yevick (PY) and modified-Verlet (MV) closures to study the equilibrium structural and thermodynamic properties of metastable
Characterizing randomness in photonic glasses using autocorrelation functions of two-dimensional images.
TLDR
A simple method to quantify randomness in photonic glasses in relation to the ideal random limit, using autocorrelation functions obtained from two-dimensional images, which would be useful in characterizing a large class of photonic random media, encompassing biological materials, radiative cooling coatings, and random lasing Photonic glasses.

Experimental observation of structural crossover in binary mixtures of colloidal hard spheres.
TLDR
A relation between crossover and the lateral extension of networks containing only equally-sized particles that are connected by nearest-neighbor bonds is suggested, supported by Monte Carlo simulations which are performed at different packing fractions and size ratios.
Decay of correlation functions in hard-sphere mixtures: structural crossover.
TLDR
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.

TLDR
The results emphasize that maximizing GFA in binary systems involves two competing effects: minimizing α to increase packing efficiency, while maximizing α to prevent demixing.
