Comments on the symmetry breaking condition in MacDowell-Mansouri action
I. Díaz-Saldaña, M. Sabido, J. C. López-Domínguez +1
In this work we study the symmetry breaking conditions, given by a (anti)de Sitter-valued vector field, of a full (anti)de Sitter-invariant MacDowell-Mansouri inspired action. We s…
An Effective Cosmological Constant From an Entropic Formulation of Gravity
I. Díaz-Saldaña, J. López-Domínguez, M. Sabido
We use the ideas of entropic gravity to derive the FRW cosmological model and show that for late time evolution we have an effective cosmological constant. By using the first law o…
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…
Comments On Torsion and MacDowell-Mansouri gravity
J. C. López-Domínguez, J. E. Rosales-Quintero, M. Sabido
Starting with the MacDowell-Mansouri formulation of gravity with a gauge group, we introduce new parameters into the action to include the non-dynamical Holst term, and t…
Towards a Supersymmetric Generalization of the Schwarzschild Black Hole
J. C. López-Domínguez, O. Obregón, S. Zacarías
The Wheeler-DeWitt (WDW) equation for the Kantowski-Sachs model can also be understood as the WDW-equation corresponding to the Schwarzschild black hole due to the well known diffe…
