While the realistic modeling of the thermodynamic behavior of fluids usually demands elaborated atomistic models, much has been learned from simplified ones. Here, we investigate a model where pointlike particles (with activity z0) are mixed with molecules that exclude their first and second neighbors (i.e., cubes of lateral size λ=3a, with activity z2), both placed on the sites of a simple cubic lattice with parameter a. Only hard-core interactions exist among the particles so that the model…

Fluid-fluid demixing and density anomaly in a ternary mixture of hard spheres.

A thermodynamic anomaly characterized by minima in isobaric curves of the total density of particles is found, yielding three surfaces of minimal density in the activity space, depending on which activity is kept fixed during its calculation.

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

Freezing phase transition in hard-core lattice gases on the triangular lattice with exclusion up to seventh next-nearest neighbor.

Hard-core lattice-gas models are minimal models to study entropy-driven phase transitions. In the k-nearest-neighbor lattice gas, a particle excludes all sites up to the kth next-nearest neighbors

Rejection-free cluster Wang-Landau algorithm for hard-core lattice gases.

We introduce a rejection-free, flat histogram, cluster algorithm to determine the density of states of hard-core lattice gases. We show that the algorithm is able to efficiently sample low entropy

Entropy of fully packed hard rigid rods on d-dimensional hypercubic lattices.

It is conjecture, based on a perturbative series expansion, that this large-k behavior of entropy per site is superuniversal and continues to hold on all d-dimensional hypercubic lattices, with d≥2.



Solution on the Bethe lattice of a hard core athermal gas with two kinds of particles.

A mixed lattice gas with excluded volume interactions only in the grand-canonical formalism with two kinds of particles, small ones which occupy a single lattice site and large ones, which, when placed on a site, do not allow other particles to occupy its first neighbors also.

Phase transitions in a system of hard Y-shaped particles on the triangular lattice.

We study the different phases and the phase transitions in a system of Y-shaped particles, examples of which include immunoglobulin-G and trinaphthylene molecules, on a triangular lattice interacting

Solution of an associating lattice-gas model with density anomaly on a Husimi lattice.

The model of a lattice gas with orientational degrees of freedom which resemble the formation of hydrogen bonds between the molecules shows very good quantitative agreement with the simulations, both for the coexistence loci and the densities of particles and of hydrogen Bonds.

Transfer-matrix study of a hard-square lattice gas with two kinds of particles and density anomaly.

Using transfer matrix and finite-size scaling methods, the thermodynamic behavior of a lattice gas with two kinds of particles on the square lattice is studied, finding a disordered phase and an ordered phase where one of the two sublattices is preferentially occupied by them.

Phase behavior of hard-core lattice gases: A fundamental measure approach

We use an extension of fundamental measure theory to lattice hard-core fluids to study the phase diagram of two different systems. First, two-dimensional parallel hard squares with edge-length σ=2 in

Global fluid phase behavior in binary mixtures of rodlike and platelike molecules

The phase behavior of a liquid-crystal forming model colloidal system containing hard rodlike and platelike particles is studied using the Parsons–Lee scaling [J. D. Parsons, Phys. Rev. A 19, 1225

Cluster-variation approximation for a network-forming lattice-fluid model.

An approximate semianalytical calculation is developed, based on a cluster-variation technique, which turns out to reproduce almost quantitatively different thermodynamic properties and phase transitions determined by the Monte Carlo method.

Entropy driven demixing in fluids of rigidly ordered particles

The entropy driven demixing in binary mixtures of rigidly ordered hard particles is studied herein. To that end, a free energy functional for this type of system, as well as an approximation for the

A dimer model on the square lattice with nearest neighbor exclusion as the only interaction shows that as the chemical potential is varied, there is a strongly discontinuous phase transition, at which the particle density jumps by about 18% of its maximum value, 1/4.

Demixing and orientational ordering in mixtures of rectangular particles.

Using scaled-particle theory for binary mixtures of two-dimensional hard particles with orientational degrees of freedom, we analyze the stability of phases with orientational order and the demixing
