A Brief Introduction to Loop Quantum Cosmology
Guillermo A. Mena Marugan
In recent years, Loop Quantum Gravity has emerged as a solid candidate for a nonperturbative quantum theory of General Relativity. It is a background independent theory based on a…
Hybrid Quantum Cosmology: Combining Loop and Fock Quantizations
Guillermo A. Mena Marugan, Mercedes Martin-Benito
As a necessary step towards the extraction of realistic results from Loop Quantum Cosmology, we analyze the physical consequences of including inhomogeneities. We consider in detai…
Dynamical Aspects of Generalized Palatini Theories of Gravity
Gonzalo J. Olmo, Helios Sanchis-Alepuz, Swapnil Tripathi
We study the field equations of modified theories of gravity in which the lagrangian is a general function of the Ricci scalar and Ricci-squared terms in Palatini formalism. We sho…
Bouncing Cosmologies in Palatini Gravity
Carlos Barragan, Gonzalo J. Olmo, Helios Sanchis-Alepuz
We consider the early time cosmology of f(R) theories in Palatini formalism and study the conditions that guarantee the existence of homogeneous and isotropic models that avoid the…
Physical evolution in Loop Quantum Cosmology: The example of vacuum Bianchi I
Mercedes Martin-Benito, Guillermo A. Mena Marugan, Tomasz Pawlowski
We use the vacuum Bianchi I model as an example to investigate the concept of physical evolution in Loop Quantum Cosmology (LQC) in the absence of the massless scalar field which h…
The combinatorics of the SU(2) black hole entropy in loop quantum gravity
Ivan Agullo, J. Fernando Barbero G., Enrique F. Borja +2
We use the combinatorial and number-theoretical methods developed in previous work by the authors to study black hole entropy in the new proposal put forward by Engle, Noui and Per…
