Time-dependent mass of cosmological perturbations in the hybrid and dressed metric approaches to loop quantum cosmology
Beatriz Elizaga Navascués, Daniel Martín de Blas, Guillermo A. Mena Marugán
Loop quantum cosmology has recently been applied in order to extend the analysis of primordial perturbations to the Planck era and discuss the possible effects of quantum geometry…
Fermions in Hybrid Loop Quantum Cosmology
Beatriz Elizaga Navascués, Mercedes Martín-Benito, Guillermo A. Mena Marugán
This work pioneers the quantization of primordial fermion perturbations in hybrid Loop Quantum Cosmology (LQC). We consider a Dirac field coupled to a spatially flat, homogeneous,…
Hybrid loop quantum cosmology and predictions for the cosmic microwave background
Laura Castelló Gomar, Daniel Martín de Blas, Guillermo A. Mena Marugán +1
We investigate the consequences of the hybrid quantization approach for primordial perturbations in loop quantum cosmology, obtaining predictions for the cosmic microwave backgroun…
