Surface Tension: Accelerated Expansion, Coincidence Problem & Hubble Tension
C. Ortiz
In this paper we give a physical explanation to the accelerated expansion of the Universe, alleviating the tension between the discrepancy of Hubble constant measurements. By the E…
Energy density profile inspired by noncommutativity
Miguel A. Garcia-Aspeitia, J. C. Lopez-Dominguez, C. Ortiz +2
An important consequence which comes from noncommutativity (NC) is undoubtedly the energy density characterized by a microscopic free parameter; indeed a Trans-Planckian parameter.…
Gravitational collapse in brane-worlds revisited
Miguel A. Garcia-Aspeitia, C. Ortiz, J. C. Lopez-Dominguez +2
This paper is dedicated to revisit the modifications caused by branes in the collapse of a stellar structure under the Snyder-Oppenheimer scheme. Due to the homogeneity and isotrop…
Scalar field in the Bianchi I: Non commutative classical and Quantum Cosmology
J. Socorro, Luis O. Pimentel, C. Ortiz +1
Using the ADM formalism in the minisuperspace, we obtain the commutative and noncommutative exact classical solutions and exact wave function to the Wheeler-DeWitt equation with an…
Non Commutative Bianchi type II Quantum Cosmology
M. Aguero, J. A. Aguilar S., C. Ortiz +2
In this paper we present the noncommutative Bianchi Class A cosmological models coupled to barotropic perfect fluid. The commutative and noncommutative quantum solution to the Whee…
(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…
