Using a linear hydrodynamic theory, we demonstrate that Faraday waves occur in liquid crystalline fluids. The use of already experimentally known material parameters of a N-(4-methoxybenzylidene)-4-butylaniline liquid crystal allows us to confirm and realize the predictions of this theory. It provides the critical wave number and necessary driving...
The path-integral representation of the Smoluchowski equation is exploited to explore the stochastic dynamics of a tagged Brownian particle within an interacting system where hydrodynamic effects are neglected. In particular, this formalism is applied to a particle system confined to a one-dimensional infinite line aiming to investigate the single-...

We present and discuss two equations of state for monodisperse systems. The first one is a general, semi-empiric, cubic equation of state
written in terms of three constant parameters and a temperature dependent function for which the second virial coefficient may be used to
obtain an analytically manipulable expression. The second equation is obta...
En esta tesis se presenta la aplicación de la teoría conocida como el formalismo Auto- consistente de la Ecuación Generalizada de Langevin (SCGLE, por sus siglas en inglés), la cual permite describir las propiedades dinámicas, de sistemas compuestos por varias especies, hacía el estado de equilibrio termodinámico o hacia un estado no ergódico carac...
By using the mean spherical approximation, we obtain an analytical expression for the static structure factor (SSF) for a monodisperse system of particles interacting through a potential given by a hard-sphere con- tribution and M Yukawa terms. This expression depends on scaling matrix Γ, which is determined by solving a set of nonlinear equations....
En este trabajo se usa un potencial efectivo de esferas duras tipo Yukawa como un modelo de interacción molecular para una mezcla binaria de gases nobles, y a partir de la teoría de funciones de distribución radial, bajo la Aproximación Esférica Media (MSA), se calculan las propiedades termodinámicas; es especial, se presenta el cálculo del potenci...
Starting from the equation of second kind of Fredholm, which models the behavior of the elastic deformation of the lithosphere under the action of vertical loads, we present an analytical expression for the deflection of the lithospheric plate in Fourier space when the constant flexural rigidity is perturbed by a cosine profile or, generally, when...
We studied with linear stability theory the Faraday waves on the surface of a smectic A liquid crystal and polymer gel‐vapor systems of finite thicknesses. Model smectic A material exhibits alternating subharmonic‐harmonic patterns of stability curves in a plot of driving acceleration versus wave number. For the case of highly viscoelastic gel medi...
We use the solution of the Ornstein Zernike equation in the mean spherical approximation to find the static structure factor for a hard spheres Yukawa fluid. The thermodynamic and the structure properties of this fluid are given in terms of an accumulative parameter Γ, which satisfies a polynomial equation of degree n⩾4. This parameter is obtained...
