Publication Top Notes

1. “Dynamical System Approach of Interacting Dark Energy Models in f(R, Tϕ) Gravity”

   • Publication: Communications in Theoretical Physics​

   • Date: April 1, 2025​

   • DOI: 10.1088/1572-9494/ad91b2​

   • Summary: This study examines isotropic and homogeneous cosmological models within the f(R, Tϕ) gravity framework, where R is the Ricci scalar and Tϕ represents the trace of the energy-momentum tensor. The authors perform a dynamical system analysis on the model f(R, Tϕ) = R + 2(aTϕ + b), deriving autonomous equations and assessing equilibrium points through eigenvalue analysis.​

2. “A Novel Approach to Baryogenesis in f(Q, Lm) Gravity and Its Cosmological Implications”

   • Publication: Nuclear Physics B​

   • Date: March 2025​

   • DOI: 10.1016/j.nuclphysb.2025.116834​

   • Summary: This paper explores the f(Q, Lm) gravity model, proposing the functional form f(Q, Lm) = αQⁿ + βLm. It discusses the model’s impact on cosmological dynamics and gravitational baryogenesis, constraining parameters using observational data from Hubble, BAO, and Pantheon datasets, and determining the baryon-to-entropy ratio ηB/s.​

3. “Cosmological Dynamics and Thermodynamic Behavior in f(Q, C) Gravity: An Analytical and Observational Approach”

   • Publication: Physics of the Dark Universe​

   • Date: February 2025​

   • DOI: 10.1016/j.dark.2024.101792​

   • Summary: This research investigates the cosmological dynamics and thermodynamic behavior within the f(Q, C) gravity framework, analyzing the viability of this modified gravity theory in explaining the universe’s accelerated expansion and other cosmological phenomena through analytical methods and observational data.​

4. “Stability Analysis of Cosmological Model in f(T) Gravity”

   • Publication: Modern Physics Letters A​

   • Date: January 20, 2025​

   • DOI: 10.1142/S0217732324502067​

   • Summary: This paper focuses on the stability analysis of cosmological models within the f(T) gravity framework, where T denotes the torsion scalar in teleparallel gravity. Using dynamical system techniques, the study evaluates stability conditions and discusses physical implications for cosmic evolution.​

5. “Dynamical System Analysis of Scalar Field Cosmology in f(Q, T) Gravity with q(z) Parametrization”

   • Publication: Gravitation and Cosmology​

   • Date: November 23, 2024​

   • Summary: This study explores the cosmological characteristics of the function f(Q, T) = αQ + β√Q + γT, with α, β, and γ as constants. By considering the deceleration parameter in the form q(z) = q₀ + q₁[z(1+z)/(1+z²)], the authors conduct a dynamical system analysis to understand the universe’s evolution within this modified gravity framework.

Conclusion

While Amit Samaddar is a promising researcher with impressive early-career achievements, the Best Researcher Award is usually granted to individuals with a well-established, long-term impact in their field. However, given his strong publication record, research contributions in cosmology, and technical expertise, he could be considered for an Emerging Researcher or Young Researcher Award, recognizing his outstanding potential in theoretical and observational cosmology.
