Noncommutative SUSY Black Holes

A. Crespo-Hernández, E. A. Mena-Barboza, M. Sabido

In this paper we propose a generalization to the Schwarzschild metric and define noncommutative SUSY black holes. We introduce the noncommutative deformation to the minisuperspace…

Noncommutative Quantum Cosmology for the FLRW model in Unimodular Gravity

J. A. Astorga-Moreno, Miguel A. García-Aspeitia, E. A. Mena-Barboza

It is well known that classical Unimodular Gravity (UG) is equivalent to General Relativity, but is not clear the equivalence at the quantum level. Here we exhibit, in the UG frame…

Asymptotically Equivalent Functions and Ultrafilters applied to Noncommutative Quantum Cosmology

J. A. Astorga-Moreno, E. Mena, Miguel A. Garcia-Aspeitia

Using the semi-classical approximation to the Wheeler-DeWitt equation obtained via Arnowitt-Deser-Misner (ADM) formalism in the Friedmann-Lemaitre-Robertson-Walker (FLRW) model cou…

The presence of a Phantom field in a Randall-Sundrum scenario

Rubén O. Acuña-Cárdenas, J. A. Astorga-Moreno, Miguel A. Garcia-Aspeitia +1

The presence of phantom dark energy in brane world cosmology generates important new effects, causing a premature Big Rip singularity when we increase the presence of extra dimensi…

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…

(Non)commutative isotropization in Bianchi I with Barotropic perfect fluid and Cosmological

C. Ortiz, E. Mena-Barboza, M. Sabido +1

We present the classical solutions to the Einstein field equations derived using the WKB-like and Hamilton procedures. The investigation is carried out in the commutative and nonco…
