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…
Effects of the ekpyrotic mechanism on inflationary phase in loop quantum cosmologies
Christian Brown, Jared Fier, Brian Phillips +2
In bouncing cosmological models, either classical or quantum, the big bang singularity is replaced by a regular bounce. A challenging question in such models is how to keep the she…
Power Law Plateau Inflation and Primary Gravitational Waves in the light of ACT
Abolhassan Mohammadi, Yogesh, Anzhong Wang
We investigate Power-Law Plateau (PLP) inflation in standard gravity and its consistency with ACT DR6 data. While many inflationary models, including the Starobinsky inflation, are…
Stable initial conditions and analytical investigations of cosmological perturbations in a modified loop quantum cosmology
Rui Pan, Jamal Saeed, Anzhong Wang
In this paper, we study cosmological perturbations in a modified theory of loop quantum cosmologies, the so-called mLQC-I model. Our purposes are two-fold: First, using a method de…
The Dynamics of Reheating in Loop Quantum Cosmology
Yogesh, Bao-Fei Li, Mayukh R. Gangopadhyay +1
In loop quantum cosmology (LQC), the initial singularity is replaced by a quantum bounce, leading to a universal post-bounce evolution characterized by three distinct epochs: bounc…
