Testing general covariance in effective models motivated by Loop Quantum Gravity
Juan Carlos Del Águila, Hugo A. Morales
In this work we introduce a criterion for testing general covariance in effective quantum gravity theories. It adapts the analysis of invariance under general spacetime diffeomorph…
On localization of universal scalar fields in a tachyonic de Sitter thick braneworld
Alfonso Diaz-Furlong, Alfredo Herrera-Aguilar, Roman Linares +2
Braneworld models may yield interesting effects ranging from high-energy physics to cosmology, or even some low-energy physics. Their mode structure modifies standard results in th…
Cosmological constraints for a two brane-world system with single equation of state
Juan L. Perez, Ruben Cordero, L. Arturo Urena-Lopez
We present the study of two 3-brane system embedded in a 5-dimensional space-time in which the fifth dimension is compactified on a orbifold. Assuming isotropic, homo…
High-order quantum back-reaction and quantum cosmology with a positive cosmological constant
Martin Bojowald, David Brizuela, Hector H. Hernandez +2
When quantum back-reaction by fluctuations, correlations and higher moments of a state becomes strong, semiclassical quantum mechanics resembles a dynamical system with a high-dime…
Super-Hopf realizations of Lie Superalgebras: Braided Paraparticle extensions of the Jordan-Schwinger map
K. Kanakoglou, C. Daskaloyannis, A. Herrera-Aguilar
The mathematical structure of a mixed paraparticle system (combining both parabosonic and parafermionic degrees of freedom) commonly known as the Relative Parabose Set, will be inv…
Casimir force in brane worlds: coinciding results from Green's and Zeta function approaches
Roman Linares, Hugo A. Morales-Tecotl, Omar Pedraza
Casimir force encodes the structure of the field modes as vacuum fluctuations and so it is sensitive to the extra dimensions of brane worlds. Now, in flat spacetimes of arbitrary d…
