Warm bounce in loop quantum cosmology and the prediction for the duration of inflation
L. N Barboza, L. L. Graef, Rudnei O. Ramos
We study and estimate probabilistic predictions for the duration of the preinflationary and slow-roll phases after the bounce in loop quantum cosmology, determining how the presenc…
Gravitational Particle Production in Loop Quantum Cosmology
Leila L. Graef, Rudnei O. Ramos, Gustavo S. Vicente
We investigate the gravitational particle production in the bounce phase of Loop Quantum Cosmology (LQC). We perform both analytical and numerical analysis of the particle producti…
Observational Constraints on Warm Inflation in Loop Quantum Cosmology
Micol Benetti, Leila Graef, Rudnei O. Ramos
By incorporating quantum aspects of gravity, Loop Quantum Cosmology (LQC) provides a self-consistent extension of the inflationary scenario, allowing for modifications in the primo…
Swampland conjecture in gravity by the Noether Symmetry Approach
Micol Benetti, Salvatore Capozziello, Leila Lobato Graef
Swampland conjecture has been recently proposed to connect early time cosmological models with the string landscape, and then to understand if related scalar fields and potentials…
Primordial gravitational waves and the H0-tension problem
Leila L. Graef, Micol Benetti, Jailson S. Alcaniz
We analyse the H0-tension problem in the context of models of the early universe that predict a blue tilted spectrum of primordial gravitational waves (GW's). By considering the GW…
Back-Reaction of Super-Hubble Cosmological Perturbations Beyond Perturbation Theory
Robert Brandenberger, Leila L. Graef, Giovanni Marozzi +1
We discuss the effect of super-Hubble cosmological fluctuations on the locally measured Hubble expansion rate. We consider a large bare cosmological constant in the early universe…
