Quintom fields from chiral anisotropic cosmology
J. Socorro, S. Pérez-Payán, Rafael Hernández-Jiménez +2
In this paper we present an analysis of a chiral anisotropic cosmological scenario from the perspective of quintom fields. In this setup quintessence and phantom fields interact in…
Noncommutative Effective LQC: inclusion of potential term
Luis Rey Díaz-Barrón, Abraham Espinoza-García, S. Pérez-Payán +1
We construct and study a simple noncommutative scheme (theta-deformation) for the effective Loop Quantum Cosmology of the flat Friedmann-Lemaître-Robertson-Walker model in the pres…
Anisotropic chiral cosmology: exact solutions
Luis Rey Díaz-Barrón, Abraham Espinoza-García, S. Pérez-Payán +1
In this work, we investigate the anisotropic Bianchi type I cosmological model in the chiral setup, in a twofold manner. Firstly, we consider a quintessence plus a k-essence like m…
Cosmological volume acceleration in dust epoch: using scaling solutions and variable cosmological term within an anisotropic cosmological model
J. Socorro, S. Pérez-Payán, Abraham Espinoza-García +1
Under the premise that the current observations of the cosmic microwave background radiation set a very stringent limit to the anisotropy of the universe, we consider an anistropic…
Noncommutative Friedmann Equations in Effective LQC
Luis Rey Díaz-Barrón, Abraham Espinoza-García, S. Pérez-Payán +1
In this work we construct a noncommutative version of the Friedmann equations in the framework of effective loop quantum cosmology, extending and applying the ideas presented in a…
Black Hole Thermodynamics from a Noncommutative Area Operator
S. Pérez-Payán, M. Sabido
One key element to calculate thermodynamical properties for a black hole is the partition function. In this paper we have incorporated the idea of a two dimensional area in a nonco…
On Deformed Phase Space and
E. Mena, S. Pérez-Payán, M. Sabido
In this letter we study the effects of a noncommutative in the phase space of an empty (4+1) Kaluza-Klein universe with cosmological constant. We analyze the effects of the noncomm…
Effects of deformed phase space on scalar field cosmology
S. Pérez-Payán, M. Sabido, C. Yee
The effects of phase space deformations in standard scalar field cosmology are studied. The deformation is introduced by modifying the symplectic structure of the minisuperspace va…
