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…
Dynamics of interacting scalar field model in the realm of chiral cosmology
Trupti Patil, Sukanta Panda, Manabendra Sharma +1
The strange behaviour of the universe's dark sector offers us the flexibility to address cosmological problems with different approaches. Using this flexibility, we consider a poss…
Background dynamics of pre-inflationary scenario in Brans-Dicke loop quantum cosmology
Manabendra Sharma, Tao Zhu, Anzhong Wang
Recently the background independent nonperturbative quantization technique has been extended to theories of gravity and the corresponding quantum effective cosmology has been deriv…
Preinflationary dynamics in loop quantum cosmology: Monodromy Potential
Manabendra Sharma, M. Shahalam, Wu Qiang +1
In this article we explore the pre-inflationary background dynamics of an FLRW universe sourced by a scalar field with monodromy potential in LQC framework. In particular we calcul…
Pre-inflationary dynamics in loop quantum cosmology: Power-law potentials
M. Shahalam, Manabendra Sharma, Qiang Wu +1
In this paper, we study the pre-inflationary dynamics for the power-law potential with in the framework of loop quantum cosmology. In the case where the…
Nonsingular Bouncing Model in Closed and Open universe
Manabendra Sharma
We investigate the cosmology of a class of model with noncanonical scalar field and matter both in FRW closed and open background. Writing the Einstein Equations in terms of dimens…
Anisotropic Bouncing Scenario in model
Sukanta Panda, Manabendra Sharma
We investigate the cosmology of a class of model with noncanonical scalar field and matter in an anisotropic time dependent background. Writing the Einstein Equations in terms of d…
Anisotropic Cyclic Universe in model
Sukanta Panda, Manabendra Sharma
We investigate the cosmology of a class of model with noncanonical scalar field and matter in an anisotropy background. We find fixed points and their stability which constraints e…
Raychaudhuri Equation in an Anisotropic Universe with Anisotropic Sources
Manabendra Sharma
In this paper we investigate the fate of the universe with an anisotropic background sourced by anisotropic matter. We see the behaviour of the Raychaudhuri Equation and investigat…
