Classical and quantum exact solutions for a FRW in chiral like cosmology
J. Socorro, S. Pérez-Payán, Rafael Hernández +2
In this work, first, we study a flat Friedmann-Robertson-Walker Universe with two scalar fields but only one potential term, which can be thought as a simple quintessence plus a K-…

Noncommutativity in Effective Loop Quantum Cosmology
Abraham Espinoza-García, Efraín Torres-Lomas, Sinhué Alejandro Pérez-Payán +1
We construct a noncommutative extension of the Loop Quantum Cosmology effective scheme for the open FLRW model with a free scalar field via a theta deformation. Firstly, a deformat…
