A Unified Rational-Function Approximation for Square-Well, Square-Shoulder, and Nonadditive Hard-Sphere Mixtures
Andrés Santos, Santos B. Yuste, Ana M. Montero +1
We develop a rational-function approximation for the structural properties of multicomponent fluids with narrow square-well and square-shoulder interactions, together with weakly n…
Thermodynamic and structural behavior of one-dimensional divalent patchy hard rods: Wertheim's first-order thermodynamic perturbation theory vs exact results
Ana M. Montero, Andrés Santos, Péter Gurin +1
We investigate the thermodynamic and structural properties of divalent patchy hard rods confined to a one-dimensional channel by modeling the bonding sites as attractive square-wel…
Exact Rheology of Uniform Shear Flow in a Gas of Inelastic and Rough Maxwell Particles
Andrés Santos, Gilberto M. Kremer
We investigate the steady uniform shear flow of a granular gas composed of inelastic and rough Maxwell particles. Exploiting the mean-field character of the model, we derive exact…
Orientational ordering and correlations in a quasi-one-dimensional hard-dumbbell fluid
Ana M. Montero, Péter Gurin, Szabolcs Varga +1
We study a quasi-one-dimensional fluid of hard dumbbells with continuous orientational degrees of freedom using an exact transfer-matrix formulation. The model allows for a complet…
Algebraic to exponential decay of spatial correlations in one-dimensional and confined hard-core fluids: A Laplace-pole analysis
Ana M. Montero, Andrés Santos
We derive the asymptotic behavior of the radial distribution function for one-dimensional (1D) hard-rod systems and related quasi-one-dimensional geometries at high packing…
Exact anisotropic properties of hard spheres in narrow cylindrical confinement
Ana M. Montero, Andrés Santos
We investigate a quasi-one-dimensional (Q1D) system of hard spheres confined within a cylindrical pore so narrow that only nearest-neighbor interactions occur. By mapping this Q1D…
Time-delayed Newton's law of cooling with a finite-rate thermal quench: Impact on the Mpemba and Kovacs effects
Andrés Santos
The Mpemba and Kovacs effects are two notable memory phenomena observed in nonequilibrium relaxation processes. In a recent study [Phys.~Rev.~E \textbf{109}, 044149 (2024)], these…
Discontinuous Structural Transitions in Fluids with Competing Interactions
Ana M. Montero, Santos B. Yuste, Andrés Santos +1
This paper explores how competing interactions in the intermolecular potential of fluids affect their structural transitions. This study employs a versatile potential model with a…
Revisiting the Laplace transform in quantum mechanics: correcting a flawed approach for the stationary Schrödinger equation
Luis M. Báez, Andrés Santos
The Laplace transform is a valuable tool in physics, particularly in solving differential equations with initial or boundary conditions. A 2014 study by Tsaur and Wang (2014 \emph{…
On a conjecture concerning the Fisher--Widom line and the line of vanishing excess isothermal compressibility in simple fluids
Ana M. Montero, Álvaro Rodríguez-Rivas, Santos B. Yuste +2
In the statistical mechanics approach to liquid-state theory, understanding the role of the intermolecular potential in determining thermodynamic and structural properties is cruci…
Exploring anisotropic pressure and spatial correlations in strongly confined hard-disk fluids. Exact results
Ana M. Montero, Andrés Santos
This study examines the transverse and longitudinal properties of hard disks confined in narrow channels. Employing an exact mapping of the system onto a one-dimensional polydisper…
Exact equilibrium properties of square-well and square-shoulder disks in single-file confinement
Ana M. Montero, Andrés Santos
This study investigates the (longitudinal) thermodynamic and structural characteristics of single-file confined square-well and square-shoulder disks by employing a mapping techniq…
Mpemba meets Newton: Exploring the Mpemba and Kovacs effects in the time-delayed cooling law
Andrés Santos
Despite extensive research, the fundamental physical mechanisms underlying the Mpemba effect, a phenomenon where a substance cools faster after initially being heated, remain elusi…
