Generalized Holographic and Ricci Dark Energy: Cosmological Diagnostics and Scalar Field Realizations
Antonio Pasqua
In this work, we present two generalized formulations of the Holographic and Ricci Dark Energy (DE) models, given by $ ρ_{GH} = 3c^2M^{2}_{pl} \left[ 1-ε\left(1-\frac{R}{H^2}\right…

A Higher-Derivative Hubble Parameter Dark Energy Model: Cosmological Analysis and Scalar Field Correspondence
Antonio Pasqua
In this work, we study a Dark Energy (DE) energy density model which depends on the Hubble parameter squared and on its first, second and third time derivatives , $\…

New HDE models with higher derivatives of the Hubble parameter
Antonio Pasqua
In this work, we investigate two Dark Energy (DE) models characterized by higher-order derivatives of the Hubble parameter , which generalize previously proposed DE scenarios. A…
