El transporte de carga en sólidos moleculares amorfos: un estudio mediante simulación de Monte-Carlo
(1993)
La invención de las técnicas electrográficas, que han dado lugar a lo que se conoce comercialmente como xerografía, ha supuesto una verdadera revolución en el campo del procesado de documentos puesto que es dicha técnica ...

Reply to ''Comment on 'Dynamical polarization potential due to the excitation of collective states' ''
(American Physical Society, 1993)
This is a reply to the preceding Comment. We confirm the results of our paper. The differences between our calculations and those of the preceding Comment come mainly from the form factors. Our random-phase-approximation-based ...

Metallicity maps of the globular cluster system in the galaxy
(IOP Publishing Ltd., 1993-01-10)
The spatial metallicity distribution in the Galaxy, as depicted by the globular cluster system, is analyzed. Two metallicity maps (on the ω - |Z| plane) corresponding to the halo and disk subsamples (Zinn 1985) have been ...

Fenómenos dinámicos en modelos sencillos que muestran comportamiento vítreo
(1993-11-27)
La pregunta ¿qué es un vidrio? No tiene una respuesta sencilla. En los experimentos reales se observa que cuando se disminuye la temperatura de una gran variedad de sustancias de un modo suficientemente rápido estas ...

First observation of scissors mode states in an odd-mass nucleus
(American Physical Society, 1993)
Nuclear resonance fluorescence experiments are reported to search for enhanced M1 scissors mode states in the deformed odd-mass nucleus Dy163. A concentration of dipole strengths near 3 MeV excitation energy is found, which ...

Threshold anomaly in non-central forces
(Elsevier, 1993)
The behaviour of the threshold anomaly for non-central potentials, which account for collective excitations in heavy-ion collisions, is investigated. It is shown that the non-central potentials should exhibit an energy ...

Normal solutions for master-equations with time-dependent transition rates - application to heating processes
(American Physical Society, 1993)
The long-time limit of the solutions of a master equation with time-dependent transition rates is analyzed, and the existence of a special (normal) solution, that all the other solutions tend to approach, is shown under ...

Molecular-dynamics ensembles: Fluctuations and correlations near the phase transitions
(American Institute of Physics Publising LLC, 1993)
Computer simulations of liquid and solid systems very close to the melting-freezing transition zone have been performed for the microcanonical, canonical, and isothermal-isobaric molecular-dynamics ensembles. Temperature, ...

Analysis of the Evans and Baranyai variational principle in dilute gases
(American Physical Society, 1993)
A variational principle for thermostated nonequilibrium steady states recently proposed by Evans and Baranyai [Phys. Rev. Lett. 67, 2597 (1991)] is analyzed by means of a model kinetic equation for dilute gases. It is shown ...
