Quantum Damping of Cosmological Shear: A New Prediction from Loop Quantum Cosmologies
Wen-Cong Gan, Leila L. Graef, Rudnei O. Ramos +2
We study the dynamics of the Bianchi I universe in modified loop quantum cosmology (mLQC-I) and uncover a robust mechanism for isotropization: the shear is dynamically suppressed a…
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…
Polymerized spacetime dynamics with multifield source: Unraveling the pre-inflationary Universe
Divya Gupta, Manabendra Sharma, Gustavo S. Vicente +2
We study a multifield model in loop quantum cosmology for a maximally symmetric spacetime governed by the Einstein-Hilbert action minimally coupled to scalar fields. Using a Legend…
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-…
Defying eternal inflation in warm inflation with a negative running
Gabriele Montefalcone, Rudnei O. Ramos, Gustavo S. Vicente +1
It was pointed out previously~\cite{Kinney:2014jya} that a sufficiently negative running of the spectral index of curvature perturbations from (ordinary i.e. cold) inflation is abl…
Quantum geometric formulation of Brans-Dicke theory for Bianchi I spacetime
Manabendra Sharma, Gustavo S. Vicente, Leila L. Graef +2
This paper investigates Bianchi I spacetimes within the Jordan frame of Brans-Dicke theory, incorporating the framework of effective loop quantum gravity. After developing general…
