Extended Local Infrared Cutoff for the Holographic Density

Abstract

We propose an extended local infrared cutoff for the holographic density that leads to linear cosmological equations and gives exact analytical solutions. The model allows to remove the residual matter and radiation-like terms of the local construction based on H and Ḣ, resulting in a clear separation between the standard cosmological fluids and the holographic sector. The homogeneous solution generates characteristic modes that give rise to different cosmological behaviors. The extension includes derivatives up to third order, where two of the characteristic modes can modify the pre-recombination expansion and reduce the sound horizon while remaining subdominant at BBN. A slightly phantom mode provides an additional late-time geometrical freedom that can further increase the CMB-compatible value of H0. Optimizations using BAO constraints yield values of H0 in the approximate range 70.5−72.4 km s−1 Mpc−1.
