Constraints on quintessence scalar field models using cosmological observations
Weiqiang Yang, M. Shahalam, Barun Pal +2
We consider a varieties of quintessence scalar field models in a homogeneous and isotropic geometry of the universe with zero spatial curvature aiming to provide stringent constrai…
Preinflationary dynamics of power-law potential in loop quantum cosmology
M. Shahalam
In this article, I mainly discuss the dynamics of the pre-inflationary Universe for the potential with in the context of loop quantum cosmology, in which…
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…
Preinflationary dynamics of attractor in loop quantum cosmology
M. Shahalam, M. Sami, Anzhong Wang
We systematically study the preinflationary dynamics of the spatially flat Friedmann-Lemaitre-Robertson-Walker universe filled with a single scalar field that has the generalized $…
Late-time acceleration with steep exponential potentials
M. Shahalam, Weiqiang Yang, R. Myrzakulov +1
In this letter, we study the cosmological dynamics of steeper potential than exponential. Our analysis shows that a simple extension of an exponential potential allows to capture l…
