Genericness of quantum damping of cosmological shear in modified loop quantum cosmology
Wen-Cong Gan, Leila L. Graef, Rudnei O. Ramos +2
In arXiv:2603.18175, the authors argue, based on numerical studies of particular cases, that the quantum damping of cosmological shear in a modified loop quantum cosmological model…
Warm Warped Throats
Dibya Chakraborty, Rudnei O. Ramos
We investigate brane inflation, focusing on warm inflation realizations within a warped throat geometry. While the standard scenario relies on a single mobile -brane moving rad…
Constraining a de Broglie--Bohm quantum bounce cosmology with Planck data
Micol Benetti, Rudnei O. Ramos, Renato Silva +1
This work investigates a singularity-free early Universe within the paradigm of quantum cosmology. We develop a bouncing model where the singularity is resolved via the de Broglie-…
Warming up the Fibres
Dibya Chakraborty, Rudnei O. Ramos
Fibre inflationary models are constructed in type-IIB string flux compactification. These models have been shown to be in agreement with the cosmological observations under appropr…
Warm multi natural inflation
Asuka Ito, Rudnei O. Ramos
Multi-natural inflation is studied in the context of warm inflation. We study the warm multi-natural inflation scenario with both linear and cubic temperature-dependent dissipation…
