A unified model of inflation and dark energy based on the holographic spacetime foam

TL;DR

This paper proposes a unified cosmological model where a scalar field representing spacetime foam energy drives both inflation and dark energy, providing a single framework for early and late universe expansion.

Contribution

It introduces a novel scalar field potential derived from holographic spacetime foam, unifying inflation and dark energy within a single model.

Findings

Potential successfully describes early universe inflation.

Potential accounts for late-time cosmic acceleration.

Model offers a unified explanation for universe's expansion phases.

Abstract

I present a model of inflation and dark energy in which the inflaton potential is constructed by imposing that a scalar field representing the classical energy of the spacetime foam inside the Hubble horizon is an exact solution to the cosmological equations. The resulting potential has the right properties to describe both the early and late expansion epochs of the universe in a unified picture.
