Particle Creation in some LRS Bianchi I models
Luis O. Pimentel, Flavio Pineda
In this work we consider particle creation by the expansion of the universe, using two Bianchi type I anisotropic models. The particles studied are of spin 0 and 1/2. The cosmologi…
Cosmologies with scalar fields from higher dimensions applied to Bianchi type model: classical and quantum solutions
J. Socorro, L. Toledo Sesma, Luis O. Pimentel
In this work we construct an effective four-dimensional model by compactifying a ten-dimensional theory of gravity coupled with a real scalar dilaton field on a time-dependent toru…
Some exact solutions in K-essence theory isotropic cosmology
Luis O. Pimentel, Carlos E. Gabarrete
We use a simple form of the K-essence theory and apply it to the classic isotropic cosmological model and seek exact solutions. The particular form of the kinetic term that we choo…
Variable cosmological term
J. Socorro, M. D'oleire, Luis O. Pimentel
We present the case of time-varying cosmological term . The main idea arises by proposing that as in the cosmological constant case, the scalar potential is identified as $ V…
Classical Bianchi type I cosmology in K-essence theory
J. Socorro, Luis O. Pimentel, Abraham Espinoza-García
We use one of the simplest forms of the K-essence theory and we apply it to the classical anisotropic Bianchi type I cosmological model, with a barotropic perfect fluid modeling th…
Gravitational potential of a point mass in a brane world
Román Linares, Hugo A. Morales-Técotl, Omar Pedraza +1
In brane world models, combining the extra dimensional field modes with the standard four dimensional ones yields interesting physical consequences that have been proved from high…
