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…

Deformed algebraic structure of angular momenta: GUP perspective
Gaurav Bhandari, S. D. Pathak, Manabendra Sharma +1
The prediction of a minimal length scale by various quantum gravity candidates (such as string/M theory, Doubly Special Relativity, Loop Quantum Gravity and others) have suggested…

Generalized uncertainty principle distorted quintessence dynamics
Gaurav Bhandari, S. D. Pathak, Manabendra Sharma +1
In this paper, we invoke a generalized uncertainty principle (GUP) in the symmetry-reduced cosmological Hamiltonian for a universe driven by a quintessence scalar field with potent…
