Constructions of Variable Modified Chaplygin-Jacobi and Chaplygin-Abel Gases from Geometrothermodynamics
Anamika Kotal, Ujjal Debnath
Understanding the physical origin of the Universe's late-time accelerated expansion remains one of the central open problems in modern cosmology. Geometrothermodynamics (GTD) offer…

Exploring the Observational Constraints and Cosmological Dynamics in f(Q,L_m) Gravity
Ratul Mandal, Anamika Kotal, Vipin Kumar Sharma +1
We explore two scenarios of gravity: linear and non-linear gravity models. The dynamical system analysis identifies two critical points for each of the propose…

Influence of Generalized Ghost Dark Energy on Wormhole Geometry
Soubhik Paramanik, Anamika Kotal, Ujjal Debnath
This article presents a wormhole solution constructed from a generalized ghost dark energy (GGDE) source in general relativity. At first, a brief review of GGDE is presented along…
