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…
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…
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…
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…
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…
