Glasslike relaxation in a one-dimensional bonded-fluid model
(American Institute of Physics Publising LLC, 1991)
A Monte Carlo investigation of the linear and nonlinear relaxation of a one-dimensional bonded fluid is presented. The simulation shows that the model possesses many of the qualitative properties of the glass-forming ...

Residual properties of a two-level system
(American Institute of Physics Publising LLC, 1991)
The residual properties, after cooling from a high temperature to T=0 K, of a system of identical and independent two-level systems are analyzed. A general criterion to know whether a given cooling law will lead to a ...

Continuous cooling of a one-dimensional bonded fluid: A Monte Carlo simulation study
(American Institute of Physics Publising LLC, 1991)
A kinetic one-dimensional bonded fluid model is formulated by extending a model for water due to Bell. The behavior of the system under continuous cooling is analyzed by use of a Monte Carlo simulation method. It shows a ...

Dynamical polarization potential due to the excitation of collective states
(American Physical Society, 1991)
Within the Feshbach formalism we calculate the nucleus-nucleus dynamical polarization potential arising from the coupling of the elastic channel to the collective vibrational states, described by the random-phase approximation. ...

Simulación por ordenador de las transiciones de fase en un modelo de cristal líquido
(1991-01)
Se presentan resultados de simulación por ordenador de fluidos gay-berne con parámetros de anisotropía k=3 y k'=5. Usando dinámica molecular en el colectivo nvt, se han identificado las fases fluidas isótropa, neumática y ...

Temperature and pressure constraints near the freezing point
(American Institute of Physics Publising LLC, 1991)
The isothermal-isobaric ensemble molecular-dynamics method MD(T,p,N) proposed by Nosé and Hoover is used to study the fluctuations in a two-dimensional Lennard-Jones fluid, close to the freezing point. The T and p constraints ...

Radiactividad natural en diversos compartimentos naturales de Andalucía
(1991)
El trabajo se ha centrado en el estudio de radionúclidos naturales, emisores alfa, en diversos compartimentos de Andalucía y puede dividirse en tres partes fundamentales. Una primera ha consistido en la puesta a punto de ...
