Donor impurity states in semiconductor zincblende nitride quantum systems as a source of nonlinear optical response
The optical absorption and the optical rectification coefficients associated to hydrogenic impurity interstate transitions in zincblende GaN-based nanostructures of the quantum wire type are investigated. The system is ...

In displacementbased design methods some demand considerations, starting from the first mode of vibration, are usually made. However, some authors have called the attention on the importance of taking the higher modes into ...
Donor-impurity-related second and third harmonic generation and optical absorption in GaAs-(Ga,Al)As 3D coupled quantum dot-rings under applied electric field
The features of some donor-impurity-related nonlinear optical properties in coupled dot-ring nanostructures are investigated with the use of the effective mass and parabolic band approximations. The electron confinement ...
Global justice, socials rights and pluralism [Justicia global, derechos sociales y pluralismo]
In this article I face one of the actual challenges that is confronting the philosophical reflection: trying to accomplish a believable defense of the moral universalism. I propose a version that attempts to expose two of ...
ON the CONSERVATION of the VERTICAL ACTION in GALACTIC DISKS
We employ high-resolution N-body simulations of isolated spiral galaxy models, from low-amplitude, multi-armed galaxies to Milky Way-like disks, to estimate the vertical action of ensembles of stars in an axisymmetrical ...
Latin American Chronicle. Is there a Boom in nonfiction literature now? [Crónica Latinoamericana. ¿Existe un Boom de la no ficción?]
The objective of this article is to determine why it is said that there is a new Boom of Latin American literature, this time in the nonfiction, through the genre of chronic. It is made with multiple interviews with ...
