Background-level reconstruction of scalar-field potentials from dark-energy histories and comparison with analytic potential families
Shahnawaz A. Adil, Miguel A. Zapata, Ãzgür Akarsu +1
The paper introduces a framework to reconstruct scalar‑field potentials that reproduce a given dark‑energy density history in a flat FLRW universe, applies it to several benchmark…

How Holographic is the Dark Energy? A Spline Nodal reconstruction approach
Miguel A. Zapata, Gabriela Garcia-Arroyo, Shahnawaz A. Adil +1
The paper investigates a generalized holographic dark energy model by reconstructing its density‑horizon relation with a spline‑based non‑parametric function and tests it against c…
