Induced cultural globalization by an external vector field in an enhanced Axelrod model
Arezky H. Rodríguez, M. del Castillo-Mussot, G. J. Vázquez
A new model is proposed, in the context of Axelrod's model for the study of cultural dissemination, to include and external vector field (VF) which describes the effects of mass me…
Analytical obtention of eigen-energies for lens-shaped quantum dot with finite barriers
Arezky H. Rodríguez, Hanz Y. Ramírez
The bound states of a particle in a lens-shaped quantum dot with finite confinement potential are obtained in the envelope function approximation. The quantum dot has circular base…
Optical transition in self-assembled InAs/GaAs quantum lens under high hydrostatic pressure
Arezky H. Rodríguez, C. Trallero-Giner, C. A. Duque +1
We present a simulation to characterize the dependence on hydrostatic pressure for the photoluminescence spectra in self-assembled quantum dots with lens shape geometry. We have te…
Uniqueness of the Fock quantization of the Gowdy model
Jeronimo Cortez, Guillermo A. Mena Marugan, Jose M. Velhinho
After its reduction by a gauge-fixing procedure, the family of linearly polarized Gowdy cosmologies admit a scalar field description whose evolution is governed by a Klein-Go…
Entire spacelike hypersurfaces of prescribed scalar curvature in Minkowski space
Pierre Bayard
We prove existence and uniqueness of entire spacelike hypersurfaces in the Minkowski space with prescribed negative scalar curvature, and with given values at infinity which stay a…
Possible cosmological implications in electrodynamics due to variations of the fine structure constant
J. L. Martinez-Ledesma, S. Mendoza
Astronomical observations are suggesting that the fine structure constant varies cosmologically. We present an analysis on the consequences that these variations might induce on th…
