LQG-modified dispersion relations and the problem of cosmic photons threshold anomalies
P. A. L. Mourão, G. L. L. W. Levy, J. A. Helayël-Neto
Our present contribution sets out to investigate how combined effects of Lorentz invariance violation (LIV) and loop quantum gravity (LQG)-modified photon dispersion relations affe…
-attractor potentials in loop quantum cosmology
G. L. L. W. Levy, Rudnei O. Ramos
We perform in this work an analysis of the background dynamics for -attractor models in the context of loop quantum cosmology. Particular attention is given to the determination…
Constraining the Barbero-Immirzi parameter from the duration of inflation in loop quantum cosmology
L. N. Barboza, G. L. L. W. Levy, L. L. Graef +1
We revisit the predictions for the duration of the inflationary phase after the bounce in loop quantum cosmology. We present our analysis for different classes of inflationary pote…
