Non-Metricity Corrections Approach to Alleviate Tension: The Logarithmic and Nonlinear Models
Rahul Bhagat, Kesava Chodavarapu, B. Mishra
The persistent discrepancy between early-time and late-Universe measurements of the Hubble constant commonly known as the tension remains one of the most pressing open questi…
Accelerating Cosmological Model with Scalar Field in Gravity
Y. Kalpana Devi, Rahul Bhagat, B. Mishra
In this work, we investigate the cosmological dynamics of gravity using two complementary scenarios: without a scalar field and with a minimally coupled genera…
Logarithmic and Strong Coupling Models in Weyl-Type Gravity
Rahul Bhagat, S. K. Tripathy, B. Mishra
In this paper, we have explored the cosmological implications of Weyl-type gravity, a modified gravitational theory formulated from Weyl geometry. The nonmetricity scalar…
Accelerating behavior from dynamical system analysis parameters
Rahul Bhagat, B. Mishra
We have performed the dynamical system analysis to obtain the critical point in which, the value of the geometric and dynamical parameters satisfy the late-time cosmic behavior of…
Effects of Matter Lagrangian in f(Q,T) Gravity: The Accelerating Cosmological Model
Rahul Bhagat, I. V. Fomin, B. Mishra
We investigate the logarithmic form of gravity with two different choices of matter Lagrangian such as: and . The parameters of th…
Exploring the Viability of Gravity: Constraining Parameters with Cosmological Observations
Rahul Bhagat, Santosh V. Lohakare, B. Mishra
In this paper, we explore the model of gravity, an extension of symmetric teleparallel gravity where the nonmetricity scalar is non-minimally coupled to the trace of t…
