Dynamic Holographic Dark Energy with Information Saturation

Key Points

This work aims to establish a cosmological framework where dark energy arises from holographic information dynamics.
Introduced a time-dependent saturation factor for dark energy information content.
Developed a modified Friedmann equation incorporating nonlinear terms of the Hubble parameter.
Conducted analytical formulation and numerical analysis for validation with representative parameters.
Proposed dark energy density is positively correlated with the rate of change of information.
Framework reproduces ΛCDM (Lambda Cold Dark Matter) model at early times.
Predicts scale-dependent dynamics for future observations.

Abstract

We propose a cosmological framework in which dark energy emerges from the dynamics of information constrained by holographic bounds 3, 4. Instead of identifyinginformation with horizon entropy, we introduce a time-dependent saturation factorξ(t), such that the total information content is I(t) = ξ(t)SBH(t). Dark energydensity is postulated to be proportional to the time derivative of this information,ρde ∝ ˙I. This leads to a modi ed Friedmann equation with nonlinear terms in theHubble parameter and its derivative. The model ensures positive dark energy density, reproduces ΛCDM at early times 9, and predicts scale-dependent dynamics.Analytical formulation, limiting regimes, and observational signatures are presented;numerical analysis is illustrated for representative parameters
