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 have also worked on the thermodynamical study of Modified Chaplygin Jacobi and Abel Gas model of dark energy. 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"
Coursework: M.Sc.
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.

Research Guide: Dr.Ujjal Debnath

Project 1: Reconstructions of f(P) and f(Q) Gravity Models from Barrow Holographic and Reconstruction of Einstein-Aether gravity from Barrow Agegraphic and New Barrow Agegraphic Dark Energy. (December 2023 - Present)

Description: In this project, I focused on the reconstruction of f(P), f(Q) and Einstein-Aether gravity theories by exploring the implications of Barrow holographic, Barrow agegraphic and New Barrow agegraphic dark energy models. Through a systematic analysis, I aimed to establish connections between these dark energy models and modified gravity theories, contributing to the understanding of the interplay between cosmic acceleration and gravity modifications.

Project 2: To Study The Thermodynamical Stability of Modified Chaplygin Abel Gas and Modified Chaplygin Jacobi Gas Models. (January 2024 - Present)

Description: The second project involves the investigation of thermodynamical stability in the context of cosmology, specifically focusing on Modified Chaplygin Abel Gas (MCAG) and Modified Chaplygin Jacobi Gas (MCJG) models. By employing thermodynamic methods, I aim to assess the stability of these models and gain insights into their viability in describing the cosmic evolution.
