Fenómenos dinámicos en modelos sencillos controlados por barreras entrópicas
(1997)
La organización de esta Memoria es la siguiente. En el Capítulo 2 presentamos una revisión somera de las principales propiedades que se utilizan para caracterizar un vidrio estructural a nivel macroscópico. Asimismo ...

Resonant behavior of a Poisson process driven by a periodic signal
(American Physical Society, 1995)
The statistical properties of the residence times of a periodically modulated Poisson process (time-dependent shot noise) on a line segment are analyzed. They show the characteristic features of a resonant behavior, which ...

Simple model with facilitated dynamics for granular compaction
(American Physical Society, 1999)
A simple lattice model is used to study compaction in granular media. As in real experiments, we consider a series of taps separated by large enough waiting times. The relaxation of the density exhibits the characteristic ...

Glassy behavior in a simple model with entropy barriers
(American Physical Society, 1997)
We study the dynamical behavior of a system with a variable number of particles n. The empty state n=0 is the ground state, while all the other states n>0 are degenerate in energy. In equilibrium, the mean number of particles ...
