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…
