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…
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…
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…
Thermal enhancement of inflationary magnetic fields
Arjun Berera, Suddhasattwa Brahma, Zizang Qiu +1
We investigate primordial magnetogenesis by assuming the gauge field is prepared in a thermal state during inflation rather than the standard Bunch-Davies vacuum. The temperature $…
Choice of Quantum Vacuum for Inflation Observables
Melo Wood-Saanaoui, Rudnei O. Ramos, Arjun Berera
We investigate the modifications to inflationary observables that arise when adopting an -vacuum instead of the standard Bunch--Davies vacuum for quantum fluctuations during in…
