Research Focus

I have conducted a study on the evolution dynamics of an inhomogeneous k-essence scalar field in my Master's Thesis. I am well experienced in reconstructing modified gravity models such as $f(P)$, $f(Q)$ and Einstein-Aether from different dark energy models like Barrow holographic and Barrow agegraphic dark energy and to study the cosmological consequences by using several cosmological parameters. I am also working on the thermodynamical study of Modified Chaplygin Jacobi and Abel Gas model of dark energy and also studying a novel alternative model to the Generalized Chaplygin Gas. My aim is to gain insights into the nature of dark energy and dark matter as well as connect the physics of the early universe to the late-time acceleration, leveraging field theoretic techniques and modified gravity models.

Thesis

Title: "To Study The Variation of Dark Energy Scalar Fields In The Homogeneous Universe Using k-Essence Scalar Field Model"
University: Sister Nivedita University
Advisor: Prof. (Dr.) Debashis Gangopadhyay
Abstract: This study explores the complex dynamics of the inhomogeneous k-essence scalar field in cosmology, specifically focusing on its implications for dark energy evolution. Through a comprehensive approach integrating Lagrangian analysis and exploration of the LTB metric, the research establishes crucial connections between dark energy components and the universe's scale factor. Key findings highlight the interplay between inhomogeneous and homogeneous aspects of the scalar field, emphasizing the influence of constants B and D on the spatial-temporal geometry. The insights contribute to understanding dark energy's origins, suggesting a singular scalar field explanation for both dark energy and accelerated cosmic expansion, offering implications for refining observational data and enhancing our comprehension of cosmic evolution.
