The Cosmological Constant as a Residual Energy in the Chaotic Inflationary Model

TL;DR

This paper proposes a novel model linking the cosmological constant to residual energy from quantum fluctuations during chaotic inflation, aligning with cosmological observations and testable by large-scale structure data.

Contribution

It introduces a unified model connecting the cosmological constant with residual inflationary energy from quantum fluctuations in a chaotic inflation framework.

Findings

Residual vacuum energy remains due to quantum fluctuations

Model aligns with observed cosmological phenomenology

Potential for empirical testing with large-scale structure data

Abstract

A new idea of the cosmological constant is proposed in this paper. Due to the horizon is limited, the quantum fluctuation of the inflaton field is not zero, a nonzero vacuum energy is remained as a residual inflationary energy of an unusual potential, however the true stable vacuum energy is zero fortunately. A unified model of the cosmological constant and the chaotic inflation is proposed, which satisfies almost all cosmological phenomenology and will can be tested by data of the cosmic large scale structure.
