Starobinsky potential and power suppression in hybrid Loop Quantum Cosmology
Marceau Henry, Guillermo A. Mena Marugán, Antonio Vicente-Becerril
We study the effect on the primordial tensor power spectrum of varying the number of e-folds during slow-roll inflation in Loop Quantum Cosmology with a Starobinsky potential. Usin…
Primodial power spectrum in loop quantum cosmology for different regularizations
Maciej Kowalczyk, Guillermo A. Mena Marugán, Tomasz Pawłowski
In Loop Quantum Cosmology, the quantization of the Hamiltonian constraint involves a regularization procedure which is affected by certain ambiguities. Moreover, different regulari…
Taming Thiemann's Hamiltonian constraint in canonical loop quantum gravity: reversibility, eigenstates and graph-change analysis
Thiago L. M. Guedes, Guillermo A. Mena Marugán, Markus Müller +1
The Hamiltonian constraint remains an elusive object in loop quantum gravity because its action on spinnetworks leads to changes in their corresponding graphs. As a result, calcula…
Asymptotic Analysis of Field Commutators for Einstein-Rosen Gravitational Waves
J. Fernando Barbero G., Guillermo A. Mena Marugán, Eduardo J. S. Villaseñor
We give a detailed study of the asymptotic behavior of field commutators for linearly polarized, cylindrically symmetric gravitational waves in different physically relevant regime…
